ARSENAL star Mesut Ozil has apologised after missing a penalty in the 2-0 Champions League defeat to Bayern Munich on Wednesday night.
The last 16 loss leaves the Gunners with a mountain to climb at the Allianz Arena on March 11, but it could have turned out differently had Ozil's spot-kick not been saved by Bayern goalkeeper Manuel Neuer in the first half.
The Gunners were reduced to 10 men when goalkeeper Wojciech Szczesny was sent off for clattering Arjen Robben in the box, and although the resultant penalty was also missed, goals from Toni Kroos and Thomas Muller did the damage.
Ozil wrote on his official Facebook account: "the next morning doesn't feel better either. sorry guys – it wasn't planned that way. outnumbered it was really hard to win against this team. #ucl #AFCvBAY"
Ozil made a promising start following his £42.5million signing from Real Madrid at the end of the summer transfer window but has struggled to make an impact lately.
German teammate Per Mertesacker believes Ozil just needs time to settle.
"Mesut has played a lot of games and he is a massive player, we need him at his best. Game by game, he will come back stronger."
Mertesacker has warned Arsenal must "switch off" from the frustration and disappointment of their Champions League defeat to Bayern Munich to avoid losing ground in the domestic title race.
Arsenal must now regroup for tomorrow's visit of relegation battlers Sunderland when Arsene Wenger's side will look to keep pace in the race for the Premier League title.
"We will concentrate on Saturday now, because we are going through a period with a lot of games," German centre-back Mertesacker said.
"We will switch off from the Champions League now and then switch on again (for the Premier League) on Saturday.
"We must keep our chins up and to think we have a chance to do again what we have done (in Munich) last year."
UEFA, meanwhile, are waiting on reports from match officials and observers before deciding whether to launch disciplinary action against Szczesny for an offensive hand gesture and on Bayern winger Robben's alleged spit in the direction of Arsenal full-back Bacary Sagna.
