LONDON (AP) -- Arsenal fell one goal short of forcing extra time against AC Milan in the Champions League, going down 4-3 on aggregate in the last 16 despite winning 3-0 in the second leg on Tuesday.
Milan, seven-time winners, advanced to the quarterfinals for the first time since winning the title in 2007. Milan crushed the Gunners 4-0 in the first leg at the San Siro on Feb. 15.
Arsenal's Laurent Koscielny found the net from a corner curled in by Alex Oxlade-Chamberlain in the seventh minute. The center back was completely unmarked from about six yards, easily heading past goalkeeper Christian Abbiati.
In the 26th minute, Theo Walcott made a bursting run down the right into the area and his tame cross was poorly cleared by Milan defender Thiago Silva. The ball landed at the feet of Tomas Rosicky, who smashed it past Abbiati to send the Emirates Stadium crowd into a frenzy.
Oxlade-Chamberlain won a penalty a few minutes before halftime after being clattered while running between Djamel Mesbah and Antonio Nocerino. Robin van Persie converted the spot kick with a shot into the top right corner.
Milan's Stephan El Shaarawy missed a golden opportunity to effectively end the two-legged series by scoring an away goal in first-half added time, pulling his shot wide when unmarked in the box.
Arsenal players were given a standing ovation when the players walked toward the tunnel at halftime.
The second half was more evenly balanced, with Milan missing a few chances to score. Wojciech Szczesny made an error with a poor clearance but Ibrahimovic misfired with the Arsenal goalkeeper off his line.
In the 77th, Nocerino's shot from the left nearly beat Szczesny, who saved with his legs.
Arsenal came close in the 59th. Gervinho was left alone to sprint down the left and he waited too long to shoot, allowing Milan's defenders to recover. He eventually fired a shot, but it deflected off Milan defender Phillipe Mexes and the 'keeper saved with his legs. Van Persie's follow-up went straight into Abbiati's arms.
Arsenal went into Tuesday's match high on confidence after coming from behind in the team's past two Premier League matches, beating Tottenham 5-2 and Liverpool 2-1. Manager Arsene Wenger has called the defeat at the San Siro "shocking" and "a disaster," saying it was the club's "worst performance in Europe by far."
