It's halftime now, but Arsenal has put themselves in a position to pull off the unlikely comeback. After going down 4-0 in the first leg at the San Siro, Arsenal would have to score at least five in the second leg today--without conceding--to advance to the next round.
Well the Gunners have come out swinging, netting their first goal 5 or so minutes after kickoff. After 45 minutes of play, Arsenal is up 3-0 (down only 4-3 on aggregate). With Milan pressing to get the all-important away goal (which would change the complexion of the match), it has been a wide open affair, with the pace of the match slowed only by questionable officiating. Sets up nicely for a thrilling second half.

That one has been a serviceable backup.
