Eduardo's 25th-minute penalty, a contentious award after he clashed with Celtic keeper Artur Boruc, extended the Gunners' two-goal first leg lead.

Emmanuel Eboue finished a sweeping move for Arsenal's second after 53 minutes and Andrey Arshavin added another two minutes after coming on as substitute.

Massimo Donati's spectacular angled volley pulled one back for Celtic, but they now go into the Europa League.

Celtic's players accused Eduardo of diving to win the crucial penalty, but the Gunners were ultimately superior to the Scottish Premier League giants and merited the victory.

Arsene Wenger's side were without injured captain Cesc Fabregas, and Wenger also chose to leave Robin van Persie and Arshavin on the bench as they held a healthy lead from the first leg.

And they could have extended the lead inside seven minutes when the normally lethal Eduardo steered wide of an open goal from close range after Boruc had saved brilliantly from Nicklas Bendtner.
