2140: There are ugly scenes at the final whistle in Valencia as both sides are involved in an on-field scuffle that made the Carling Cup final bust-up look like a huge love-in. Valencia's celebrations seem to upset Inter and it ends up with punches thrown and players from both sides squaring up all over the pitch. There are sure to be ramifications from Uefa, particularly as Valencia substitute David Navarro is seen to enter the melee late on to throw a punch at Nicolas Burdisso. The battle continues off the pitch and outside the dressing rooms before security guards arrive to try and separate the sides.
2138: FULL-TIME Chelsea 2-1 Porto

2135: FULL-TIME Liverpool 0-1 Barcelona
Liverpool lose on the night but nobody in Anfield cares a jot as they knock the European champions out on away goals.
2134: Into the last minute of added on time at Anfield and Liverpool just need to play out time. Chelsea need to get through four minutes of stoppage time.
2133: Peter Crouch misses a great chance to level when he is picked out by Jermaine Pennant but he volleys just over.
2131: We have three minutes of injury time at Liverpool and Valencia and we are also into stoppage time at Lyon.
2129: Barcelona are testing Liverpool with plenty of long balls and corners. The Reds respond by throwing on Peter Crouch for a late run-out.
2126: It promises to be a nervous final five minutes at Anfield, for the second time in four days. Eidur Gudjohnsen threatens a second but Steve Finnan just manages to hook his leg to a penetrating ball into the box.
2124: Liverpool have turned defence into attack as Steven Gerrard finds some extra energy from somewhere before testing Victor Valdes.
2123: GOAL Chelsea 2-1 Porto
Maybe we aren't heading for extra-time after all. Ashley Cole and Didier Drogba set up Michael Ballack to swivel and fire home.
2122: Chances have dried up at Stamford Bridge and it has extra-time written all over it.
2120: Liverpool's fans are doing their bit as their 10 outfield players are pretty much camped in their own half. This could be a tough 12 minutes for the Reds.
2118: Barcelona threaten a second as Ronaldinho fires in a low shot that Jose Reina gets down to save well.
2116: GOAL Liverpool 0-1 Barcelona
What an impact by Eidur Gudjohnsen, who gives the European champions a lifeline. Lionel Messi slips in a pass and Gudjohnsen keeps his head to round Jose Reina and slot home. Game on.
2114: Liverpool skipper Steven Gerrard tests Victor Valdes with a powerful shot from a difficult angle, which the keeper just manages to deal with.
2112: Barcelona, needing two goals in 20 minutes, bolster their attack with former Chelsea star Eidur Gudjohnsen coming on for Lilian Thuram.
2110: Chelsea also make a change with Lassana Diarra, who is on a booking, being replaced by Paulo Ferreira.
2109: Craig Bellamy has done his bit and is replaced by Jermaine Pennant. It looks like they will go with just Dirk Kuyt up front and Steven Gerrard looking to support him from midfield.
2107: A couple of worries for an overworked Chelsea physio as midfielder Michael Ballack and Andriy Shevchenko require treatment. The magic sponge seems to do the trick as both men continue.
2105: Chelsea's Lassana Diarra goes into referee Roberto Rosetti's book for a late tackle on Ricardo Quaresma.
2103: We have played just over an hour at Anfield but the game appears in no danger of slowing down. The pace seems to suit Liverpool and Dirk Kuyt fires just wide from outside the area.
2102: Samuel Eto'o goes off for Barcelona after a fairly uninspiring evening.
2102: Porto give the ball away but Didier Drogba fails to punish them as they fires over.
2101: Porto are going for broke as they make a double substitution, bringing on Brazilian pair Ibson and Adriano.
2100: Barcelona are looking much more dangerous this half and Lionel Messi tests Jose Reina with a left-foot shot.
2059: Liverpool open up the Barcelona defence with Dirk Kuyt playing in Steven Gerrard but he opts for a quick shot and it is wide of the post.
2056: Craig Bellamy appears to take an elbow in the face from Lilian Thuram. The Welshman looks a bit shook up but he is able to continue.
2054: Just over 52 minutes into the game and Ronaldinho comes to life, when he turns just outside the box and glides past a couple of challenges before shooting against the post. A quick warning from the Brazilian.
2052: GOAL Chelsea 1-1 Porto
Chelsea are back on level terms thanks to an absolute howler from Porto keeper Helton. He allows a scuffed long-range shot from Arjen Robben to squirm over his body and into the net.
2048: Kicking towards the Kop, Liverpool are close to an early second-half goal but Craig Bellamy fails to react to a Steven Gerrard cross and cannot direct it on target.
2047: All four games are back up and running.
2046 PLAYER RATER: Ricardo Queresmo leads the way at Stamford Bridge with a rating of 7.75, with Didier Drogba Chelsea's best offering on 7.63.
2041 PLAYER RATER: Liverpool's first-half dominance is reflected in your player ratings. Seven of Barcelona players have a rating of less than six out of 10. The star men for Liverpool have been John Arne Riise (7.82) and Jamie Carragher (7.79) so far.
2032 HALF-TIME: We are at half-time around Europe. It is bad news for Lyon who need three second-half goals to progress. Mixed fortunes for the home sides as Chelsea are down by a goal, but Liverpool have been awesome at Anfield. All quiet between Valencia and Inter Milan as yet.
2029 GOAL Lyon 0-2 Roma
Roma take a giant stride towards the Champions League quarter-finals courtesy of a fine individual goal from Mancini. The Brazilian does a fine Cristiano Ronaldo impression with a stepover masterclass before lashing past Gregory Coupet.
2027: Ronaldinho finally finds a bit of space in the central midfield area and his driving run finds Samuel Eto'o on the left side of the box, but Jamie Carragher pinches the ball off him.
2025: Liverpool are giving Ronaldinho and co no time at all on the ball and their plan is working a treat so far.
2022: Lyon miss a good chance to equalise when Sidney Govou heads off target from a good position.
2021: Barcelona have their effort at goal, but Ronaldino's volley from the edge of the box is well off target.
2019: Chelsea winger Arjen Robben tricks and turns his way into the area and goes to ground dramatically under a challenge from Jorge Fucile, but the Dutch flyer is booked for diving. Replays show there was no contact.
2016: Drama galore at Anfield as a Victor Valdes scuffed clearance falls for Momo Sissoko who shoots first time and is denied a stunning goal by the crossbar.
2013: Two chances in two minutes for Chelsea. First Michael Ballack fails to connect on a shot and then Andriy Shevchenko lines up Frank Lampard only for the England midfielder to mis-control in front of goal.
2010: Liverpool are agonisingly close to an opener as Victor Valdes makes a bit of a hash from a Craig Bellamy effort but then saves well from Dirk Kuyt before John Arne Riise has a header cleared off the line.
2009: Chelsea leading scorer Didier Drogba is close to an equaliser but Bruno Alves comes to Porto's rescue.
2007 GOAL Lyon 0-1 Roma:
Roma are in front through Francesco Totti. Max Tonetto swings in a left-wing cross and Totti is free as a bird to head down and past Gregory Coupet.
2006: Chelsea have upped their game but there are already signs of frustration. Manager Jose Mourinho is out of his dug out for the first time to try and calm his men down.
2004: Deco is brought to ground by a reckless challenge from Momo Sissoko and he is rightly booked for the lunge. The caution means Sissoko will miss the first leg of the quarter-final if the Reds go through.
2002: That is the first goal scored by a European team at Stamford Bridge this season. The last team to do it was Barcelona, who ended their hopes in the competition.
2000: GOAL Chelsea 0-1 Porto
Oh dear. Perhaps Chelsea were too busy celebrating that 10-hour achievement as Ricardo Quaresma beats their offside trap and runs on to slip it under Petr Cech.
1959: Obviously it takes something a little bit special to beat the Blues at the Bridge. The last man to do it? John Murphy of Macclesfield of course.
1957: Not much going on over at the Bridge, but Chelsea have just made it to 10 hours without conceding a goal at Stamford Bridge.
1956: Barcelona are slow learners as John Arne Riise is again allowed to get a shot away. He is getting closer as this effort slaps against the crossbar with Barca keeper Victor Valdes well beaten.
1955: Signs of nervousness in the Barcelona side as they attempt to play it out from the back and Carles Puyol is forced to hoof it clear.
1953: John Arne Riise gets another sight on goal and this time he flashes his shot just wide of the upright from the edge of the area. It is promising for Liverpool so far.
1951: John Arne Riise is given a bit of space to shoot but unless he is well off target. Unless his target was the corner flag, which he just missed.
1949: Chelsea owner Roman Abramovich may not turn up to Carling Cup parties, but he is rarely missing for a big game and he has taken up his usual uncomfortable-looking stance in the Stamford Bridge stands.
1947: Liverpool look as if they have started the game like the away team, but they nearly catch Barca out on the break but Steven Gerrard's throughball is just too long for Dirk Kuyt.
1946: Chelsea striker Andriy Shevchenko is straight into the action as he drills in a right-foot shot from the left corner of the box that is just over.
1946: And Chelsea-Porto are not far behind them.
1945: Barcelona get their game under way at Anfield, while we are off an running at Valencia and Lyon.
1942: It is not all about Liverpool though as Chelsea come out at Stamford Bridge for their second leg with Porto. The club have handed out 40,000 blue scarves to their fans and they all get a good waving as stand-in skipper Frank Lampard leads them on to the field.
1939: Liverpool fans belt out "Walk on" at Anfield, sounds like it is going to be a cracking atmosphere.
1937: Liverpool have five survivors from that game in their squad this evening - Dudek, Carragher, Hyypia, Riise and Gerrard. Barcelona just one - Jose Reina, who was on the bench for Barcelona that day but now stands between the Spanish giants and a place in the Champions League quarter-finals.
1934: It is five and a bit years since Liverpool hosted Barcelona at Anfield. Reds fans will be hoping there is no repeat of that game as Barca ran out 3-1 winners.
1931: Barcelona look like they will throw everything at Liverpool with Samuel Eto'o joining Ronaldinho and Lionel Messi in attack.
1930: Meanwhile the biggest clash of the evening is almost certainly taking place at Anfield, where the last two winners of the competition go head-to-head.
1929: Three of the four games are perfectly poised, with the first leg ties unable to separate the teams.
1925: So the teams are in and we are all set for a fascinating night of European football.
Liverpool manager Rafael Benitez names the same team that earned a 2-1 advantage from the Nou Camp. Barcelona make four changes from the first leg tie with the biggest news being that Samuel Eto'o starts, while Lilian Thuram, Andres Iniesta and Olegeur also return.
Chelsea boss Jose Mourinho picks the same side that started against Portsmouth at the weekend, with Ashley Cole set to make his 50th Champions League appearance. Porto defender Jose Bosingwa is replaced by Slovakian Marek Cech after picking up a thigh injury, while Paulo Assuncao replaces Helder Postiga in attack.
Lyon are without the suspended Jeremy Toulalan while Sylvain Wiltord and Karim Benzema have to settle for a place on the bench. Roma bring back the fit-again Rodrigo Taddei while Mirko Vucinic has shaken off an ankle injury to start.
Valencia are at full-strength, making only one change from the first leg as Ruben Baraja replaces fellow midfielder David Albelda. Runaway Serie A leaders Inter Milan make two changes from the 2-2 draw, with Maxwell and Olivier Dacourt coming in for the injured Esteban Cambiasso and Luis Figo, who is on the bench.
