2121 BST: Arsenal 2-1 Man Utd
There is nothing lucky about Thierry Henry's second as he picks up the ball on the edge of the box, spins, strides goalwards and slides the ball past Fabien Barthez.
United fans are convinced Henry was offside.

(Van Nistelrooy, 24 mins)
2046 BST: Arsenal spring to life - Ljungberg causing problems in the box again - though it is his deflection that takes Robert Pires' shot over the bar.
2045 BST: Arsenal get their first sniff of goal - but United skipper Roy Keane is on hand to clear the ball off the tip of Ljungberg's boot.
2042 BST: Manchester United are growing in confidence - they are winning the midfield battle and O'Shea is beginning to make forays down the left flank.
2035 BST: Patrick Vieira loses his battle against injury and, nursing his heavily-strapped right leg, is substituted for Edu.
2025 BST: Arsenal 0-1 Man Utd
Ruud van Nistelrooy breaks down the left hand side after a one-two with Ryan Giggs.
Martin Keown can't catch him as he hares in on goal and the Dutchman tucks the ball neatly over the diving Stuart Taylor.
2022 BST: Again the Arsenal defence are caught flat as Van Nistelrooy darts forward to meet a Paul Scholes flick but his first-time clip lands of the roof of the net.
2021 BST: With 20 minutes gone, United have had the only chance of the game but Arsenal have had the lionshare of possession. Both sides are fired up but not risking much.

2013 BST: Henry breaks dangerously down the Arsenal right but Keane gets back to cut out his low cross.

But he doesn't get enough contact and the ball skims wide.

2005 BST: Both sides begin keenly, jousting cautiously in midfield in front of the packed Highbury crowd.
2001 BST: Arsenal and Manchester United kick-off at Highbury in the biggest match of the Premiership season.
The Gunners are without David Seaman who is suffering from flu.
Stuart Taylor replaces Seaman in the Arsenal goal.
That is one of five changes made by Arsene Wenger with Pires, Henry, Bergkamp and Gilberto returning.
As expected, Vieira shrugs off his weekend knock ready to lead the side out.
Manchester United are unchanged from the side that thumped Newcastle - which means David Beckham and Neville stay on the bench.
Keane passed a late fitness test to join hat-trick hero Scholes in midfield, with Solskjaer playing wide right.
A win would put Arsenal top of the Premiership on goal difference - with a game in hand with four weeks of the season remaining.
