Bayern Munich have dealt Arsenal a second successive 5-1 hammering to reach the Champions League quarter-finals 10-2 on aggregate at a stunned Emirates Stadium.
Striving to become the first team in Champions League history to overturn such a deficit, Arsenal actually led Tuesday's encounter at halftime through a Theo Walcott goal.
But once Robert Lewandowski equalised from the penalty spot and Arsenal skipper Laurent Koscielny was sent off, the Bundesliga leaders ran amok.
Robben capitalised on a defensive mistake in the 68th minute before substitute Douglas Costa curled in a third to send Arsenal's fans streaming towards the exits.
Bayern were not finished though and Arturo Vidal struck twice as Arsenal slumped to their worst home defeat since 1998 and a seventh successive elimination at the competition's last-16 stage.
Arsenal fans had mounted a small-scale demonstration calling for an end to manager Arsene Wenger's 21-year reign at the club before kickoff - yet there was plenty to admire from his team in the first half.
In his program notes Wenger called for a salvaging of pride after Arsenal's second-half capitulation in Germany.
Alexis Sanchez was restored to the starting lineup after being dropped against Liverpool and when Walcott smashed in a 20th-minute opener, it seemed they would at least exit with heads held high.
Olivier Giroud, pressed into action immediately before kickoff when Danny Welbeck injured himself in the warm-up, wasted a great chance to make it 2-0 straight after the interval.
Then it all went horribly wrong for Arsenal and turned into a personal nightmare for Wenger whose position will again come under intense scrutiny.
Bayern levelled when Lewandowski was pushed over while running into the box by Koscielny in the 55th minute.
Referee Tasos Sidiropoulos reached for his red card, ending Koscielny's evening and Arsenal swiftly collapsed, as they did when the French defender went off injured in the first leg.
Lewandowski sent David Ospina the wrong way from the spot and Robben then capitalised on some poor defending before Costa netted in the 78th minute.
Bayern fell just short of matching their 11-goal margin over two legs against Sporting Lisbon in 2009 when they won 12-1.
