AC Milan might have looked overmatched for long, long spells of the first half, but they've probably been the better side in the second. Barcelona are being a little bit sloppy at both ends of the pitch now, giving away possession too easily ont he attack and letting Zlatan Ibrahimovic bully them when the hosts come forward, and that means that Milan can relax a little bit, holding possession in the visitors' half.
Barcelona look rattled, and they're being forced into rather aimless punts forward, which isn't like them at all. They'll need to settle down here or Milan look reasonably likely to shut them out (or even score a goal of their own), which would be a great result. This, of course, means that a Barca goal is imminent. On cue, Cristian Tello, who's on for Andres Iniesta, smacks the ball into the side netting.
