Arsenal 0-0 Milan

Finds a bit of space and fires in a shot from 20 yards that deflects behind for a corner. Much worse, Toure is limping off.

6 min: Lehmann! Catches the corner and hurls the ball 60 yards to Adebayor, pursued by five defenders. Arsenal corner, but Adebayor kicks Kaladze in the head and it's a free kick.

7 min: Senderos on for Toure. Bit of a blow this.

9 min: Long ball to Adebayor. Brilliant control and plays in Eboue on the right. Decent cross but Adebayor's header is easily saved. Some sneaky leaning-in-style defending from Nesta there.

11 min: Eduardo is playing on the left by the way. Adebayor up on his own.

12min: Nice spell of possession from Arsenal. Adebayor looks well up for this. Maldini dives in on Eboue. Corner.

13 min: Corner just evades Senderos and is hacked clear.
