GOALFLASHES AND MAJOR INCIDENTS (all times GMT)
2136: FULL-TIME Real Madrid 3-2 Bayern Munich
Goals, goals, goals. The second 45 was quieter than the first, but that late Bayern Munich effort means a 1-0 win in Germany would be enough for Owen Hargreaves and co.
2136: FULL-TIME Lille 0-1 Manchester United
A priceless away victory in a match featuring a first-half crush scare, a controversial second-half goal and the threat of the Lille team walking off in a French farce of a finale.
2135: FULL-TIME Celtic 0-0 AC Milan
The Bhoys remain unbeaten at home in Europe this term. Now they have to win or draw for the first time away from home in Europe this term when they go to Milan.
2132: Three minutes of added time for Celtic to find a winner.
2131: FULL-TIME PSV Eindhoven 1-0 Arsenal
Carnival time for the home fans, while Arsenal have it all to do in the return at the Emirates. The Gunners have failed to score in either of their last two games and next up is Chelsea in the Carling Cup final.
2130: GOAL Real Madrid 3-2 Bayern Munich
That is a potential lifeline for the Germans as former Barcelona man Mark van Bommel pounces on a loose clearance and cracks in a volley from the edge of the area. He incorporates an abusive gesture in his celebration.
2127: About half of the Lille team were by the touchline, but quick discussions have got things going again. Missiles are raining down on to the pitch. A stick. A big scrunched up piece of paper. Not exactly missiles of the military type, more like objects.
2126: Blimey, Lille are walking off in a huff.
2125: GOAL Lille 0-1 Manchester United
And there it is. A quick free-kick from Ryan Giggs catches Tony Sylva offguard on his right post lining up the wall. The ball goes in nearer the left post and Sylva is booked for complaining vociferously.
2124: Surely there has to be another goal somewhere.
2123: A chance for Lille and Johan Audel is holding his head in his hands after failing to turn in a cross from close range. Sir Alex Ferguson is doing his nut on the touchline.
2122: Massimo Ambrosini is unable to control a long ball in the box for AC Milan and the chance is gone for the Italians almost as quickly as it appeared out of nothing.
2121: A sensational save by Iker Casillas from Claudio Pizarro.
2120: It is an open game in Lens, but those odds on Manchester United scoring the first goal have drifted. 'No Goal' is the new favourite.
2118: Arsenal, who enjoyed more possession than any other team in the group stages, have had the majority of the ball at the Philips Stadion but they seem unable to do the key thing with it - put it in the net.
2116: Tony Sylva fails to graps a low Wayne Rooney cross and the ball breaks for Henrik Larsson. But the Swede is unable to get a shot away immediately, is pushed wider and wider before chipping an effort over the bar.
2115: Bring on the Beast. Julio Baptista replaces Alexander Hleb for Arsenal.
2112: Quite remarkable. You will never see a more blatant diive than that from Alberto Gilardino. Four steps after he evades a tackle in the box and the ball racing away ahead of him he lunges for the turf. Where are the prim and proper judges to mark that? Definitely a 6.0. And a yellow card. He gets the booking, but not the top marks.
2111: Pancakes are quick cookers so that is a bad analogy, but the action is simmering up nicely. Peter Odemwingie fires an effort just wide for Lille.
2109: Tomas Rosicky slips a reverse pass to Cesc Fabregas on the edge of the PSV box and it takes a tremendous, high save from Gomes to maintain the Dutch side's advantage.
2108: A change for Manchester United, and a strange one as well. Louis Saha replaces Cristiano Ronaldo with a quarter of the game to go.
2105: Sun Xiang is coming on for PSV Eindhoven. Who's he you ask? Only the first Chinese player to be called into Champions League action... ever.
2104: A goal at Lens as well, but no. Peter Odemwingie is judged to have pushed Nemanja Vidic as he headed in. What a let off for Manchester United.
2101: GOAL PSV Eindhoven 0-1 Arsenal
What a shot. The ball breaks for Edison Mendez outside the area and he cracks of a low shot before Gilberto Silva can close him down and the effort goes in at Jens Lehmann's right post.
2100: Another Shunsuke Nakamura free-kick in a dangerous position, but that is not one of his best. The Japanese midfielder fails to test the goalkeeper.
2058: It is that man Mathieu Bodmer again for Lille. He somehow ghosts inbetween Rio Ferdinand and Nemanja Vidic in the area and pokes an effort on goal which Edwin van der Sar blocks.
2055: PSV Eindhoven are showing more ambition after the interval and posing some problems for Arsenal.
2053: Chances left, right and centre. In no particular order, Wayne Rooney volleys over for Manchester United, Arouna Kone volleys wide for PSV Eindhoven, Gennaro Gattuso slides an effort past the post for AC Milan and Lee Naylor lashes an effort over at the other end for Celtic, while Oliver Kahm denies David Beckham.
2052: Uefa, the Football Association and Manchester United are going to have a meeting after the match in Lens about the over-crowding in the away end.
2051: And this is it for Manchester United, the bookies rarely get it wrong. Wayne Rooney breaks down the left and digs out a cross but Ryan Giggs is unable to get on the end of it.
2050: You can get the longest odds on Celtic scoring the first goal by a British side tonight. At the other end of the scale are Manchester United.
2049: As in the first-half, Real Madrid and Bayern Munich bring up the rear, so to speak.
2047: And the action gets going again at Celtic Park and the Stade Felix Bollaert.
2045: Maybe the players are keen to get to that carnival in town in Eindhoven. They are the first to resume.
2043: And news from Lens. It seems that there was only one gate open into the bottom tier which caused a crush around that area, when there was space along the way. After a few fans tried to climb over the fence the gendarmerie went for the tear gas.
2040: A bit more on Carnival in Eindhoven, or 'Carnaval' as the locals spell it. It happens the day before lent and you get what you'd expect at a carnival - food, drink, parades, fun and festivities.
2035: That third Real Madrid goal has now been credited to Raul.
Player rater: Thierry Henry (8.09) is leading the way among the 33 players turning out for British teams. In fact, he leads the way full-stop in the matches featuring British sides. His nearest challenger is fellow Arsenal striker Emmanuel Adebayor (8.08). Manchester United's leading man is Cristiano Ronaldo (7.81) while Artur Boruc is in top spot for Celtic.
2033: HALF-TIME Real Madrid 3-1 Bayern Munich
Well, that's the place to be.
2032: HALF-TIME Lille 0-0 Manchester United
And another British team at deadlock, although you get the feeling the visitors look the likelier to score... especially after Sir Alex Ferguson gives his half-time hairdryer an airing.
2032: HALF-TIME Celtic 0-0 AC Milan
Bits and bobs at each end but no clear cut chances really.
2031: HALF-TIME PSV Eindhoven 0-0 Arsenal
Not a great deal to cheer the travelling support as PSV play a patient game. But Gooners now have only about an hour to go before they can get involved in Eindhoven's carnival.
2029: Manchester United have enjoyed much of the possession against Lille but Edwin van der Sar is having a go at his defence as they stand off Mathieu Bodmer who sends a daisy cutter wide of the target.
2027: Thierry Henry has a shot on target for Arsenal. He pirouettes away from his defender on the edge of the box but his snap volley is well parried by Gomes.
2026: Chaos in the Lille box. Keeper Tony Sylva tips an effort off Henrik Larsson's boot and Cristiano Ronaldo sees his follow-up effort blocked by frantic defenders.
2024: David Beckham is not the only player on show with deadeye delivery. Shunsuke Nakamura whips a free-kick in on goal which Zeljko Kalac saves with a flourish for the cameras.
2023: Who cares about British teams when all the fun is to be had in Spain? Roy Makaay is through on goal but Iker Casillas saves the volley with his legs.
2022: That is two assists for David Beckham. Is that the Beckham for England bandwagon being packed up for an outing to the back pages.
2021: GOAL Real Madrid 3-1 Bayern Munich
It will have to be some comeback. David Beckham's flat, fierce free-kick is side-footed in by Ruud van Nistelrooy.
2017: Owen Hargreaves is back in the action for Bayern Munich at Real Madrid. Maybe the column will be about his startling contribution to a comeback win instead.
2016: Tomas Rosicky has another chance for Arsenal, although this one is harder. From the edge of the area he jinks left then right before curling a shot just wide of the target.
2015: GOAL Real Madrid 2-1 Bayern Munich
If you want goals Madrid's the place to be. Ivan Helguera gets his head on David Beckham's corner and loops an effort into the top corner - although it is debatable how much he actually knew about it. It is also debatable as to whether he will be credited with the effort as Raul inched in at the post and could have got the killer touch.
2013: The gold-booted Owen Hargreaves hobbles off for Bayern Munich after being caught by Roberto Carlos. Hopefully his next column for the BBC Sport website will not be centred on the Spanish helath system after a night in hospital.
2011: Alberto Gilardino springs the offside trap on the left for AC Milan and looks to steer the ball in from an acute angle on the left, but Celtic stopper Artur Boruc gets a vital touch with his foot and the effort trickles wide of the goal.
2009: GOAL Real Madrid 1-1 Bayern Munich
It is all square in Spain. Lucio meets Willy Sagnol's deep free-kick with a quite brilliant header back acorss goal and in in at the post.
2008: A third corner of the night for Manchester United and you will get long odds on them having a worse one! Ryan Giggs went for the driver when he needed a more lofted club.
2005: The local gendarmerie seem to have the kerfuffling in the away end under control at Lens. BBC Five Live's Dave Woods reckons they opted for tear gas.
2004: Ryan Giggs looks to go on his own when a pass would have been the better option. But Manchester United soon get a chance, with Wayne Rooney firing over.
2002: Arsenal are really slipping through the gears. They are not in fifth quite yet but the ball is pinging around this way and that. It is dexterity of the footballing kind.
2000: Trouble off the pitch in Lens where there seems to be a bit of disturbance in the away end. The game's still going on.
1958: And almost a goal for Arsenal against PSV Eindoven. Thierry Henry plays in Tomas Rosicky on the left of the box and his shot is half saved by Gomes before Carlos Salcido clears.
1956: GOAL Real Madrid 1-0 Bayern Munich
Ruud van Nistlerooy bisects the Bayern defence with a threaded pass which Raul latches on to. As he looks to round Oliver Kahn the keeper gets a touch to the ball but the rebound is slotted in.
1954: Sloppy play from Cesc Fabregas but fortunately for him PSV Eindhoven's Diego Tardelli's first touch is equally poor and a chance goes begging.
1953: Jan Vennegor of Hesselink shakes off his markers in the AC Milan box but cannot get a touch on Shunsuke Nakamura's free-kick. The slightest of touch could have resulted in a goal with only the keeper Zeljko Kalac to beat.
1951: The rain in Spain falls mainly in the plain. It is bucketing it down in Madrid, where Ruud van Nistelrooy fires over for Real Madrid.
1949: Cristiano Ronaldo goes for an early attempt at his own stepover record for a footballer on French soil, but after all the fancy stuff his square pass goes straight to a Lille player.
1948: Former Rangers midfielder Gennaro Gattuso is getting a right old welcome at Celtic Park from the home faithful.
1947: It is all a bit more relaxed in the Spanish capital. Bayern Munich eventually get the game going against Real Madrid.
1946: Well PSV Eindhoven have done better than they did in 2002 when they conceded a goal to Arsenal within 20 seconds.
1945: Lille and Manchester United are the first to get the ball rolling, closely followed by the other two games involving British sides.
1943: Change strips for Arsenal and Manchester United. The Gunners are wearing that bright yellow strip, while the Red Devils are all in white.
1942: And now it is the turn of the Champions League anthem around the grounds. Game on... almost.
1941: There's the customary rendition of "You'll Never Walk Alone" at Celtic Park which makes the hairs on the back of your neck stand on end. "Chelsea Dagger" by the Fratellis does not have quite the same impact in Eindhoven.
1939: While Manchester United have a patchy record against Lille, Arsenal can boast an unbeaten reacord against PSV Eindhoven. Four matches and two wins for the Gunners.
1935: Last season it was the Stade de France in Paris and this time the Lille v Manchester United match is being played at the Stade Felix Bollaert in Lens. All this because Lille's own ground does not meet Uefa standards.
1932: Lille are the tournament's outsiders but Manchester United will not be taking them lightly. Sir Alex Ferguson's side lost to the French last season and their hosts include nine of the team that won 1-0 at the Stade de France.
1929: Since the group stage of the tournament Bayern Munich have changed coaches with Ottmar Hitzfeld replacing Felix Magath. The Germans will be hoping the new man can find that magic touch which helped him lead Borussia Dortmund and Bayern to the Champions League title in 1997 and 2001 respectively.
1925: You can listen to Celtic v AC Milan on BBC Radio Five Live.
1924: Roddy Forsyth has used that astounding fact to help highlight the potential significance of Celtic Park's "intimidating" atmosphere which can "surprise even the most experienced players".
1923: And here's to another legend, the BBC's supremo on Scottish football Roddy Forsyth. On cue he comes out with a cracker of a stat. AC Milan duo Paolo Maldini and Andrea Pirlo have played more Champions League matches between them than the whole of the Celtic side!
1922: A special mention for Paolo Maldini who is making his 100th Champions League appearance tonight. The 38-year-old AC Milan legend joins Raul, Roberto Carlos, David Beckham and Oliver Kahn in the 100-club.
1920: But wins are not the be-all and end-all for the home sides. A goalless draw is a pretty handy result in these two-legged affairs for teams to take on the road in a fortnight.
1918: It is Shrove Tuesday and shrove means 'to grant absolution'. If there are mistakes that will be in short supply from fans who will be left as flat as a pancake.
1915: Four games, three British teams, two from England, one from Scotland and no time for mistakes tonight as the Champions League gets serious.
Striker Jan Vennegor of Hesselink is passed fit for Celtic and will play alongside Kenny Miller. The cup-tied duo of Steven Pressley and Paul Hartley are replaced by Darren O'Dea and Evander Sno. AC Milan cannot select Ronaldo, who is also cup-tied, and Alberto Gilardino leads the line.
Henrik Larsson makes his first Champions League appearance since last season's final. He partners Wayne Rooney in the Manchester United attack, while at the back Edwin van der Sar is fit to play in goal. Key man Mathieu Bodemer is fit for Lille.
William Gallas starts at right-back for Arsenal, with Emmanuel Eboue and Justin Hoyte out injured. Alexander Hleb returns on the right of midfield, one of six changes from the side that drew to Blackburn. A boost for the Gunners is the absence of Jefferson Farfan in the PSV Eindhoven attack.
David Beckham plays for Real Madrid, who are without Sergio Ramos and Mahamadou Diarra, and Gonzalo Higuain is in the attack alongside Raul and Ruud van Nistelrooy. Bayern Munich also feature an Englishman in Owen Hargreaves, and start with Roy Makaay and Lukas Podolski in attack.
