The Gunners' club-record signing took to his Facebook page to express his sorrow and regret for a poor performance in the 2-0 reverse.
Mesut Özil endured a torrid evening against Bayern Munich last night, suffering criticism from Arsenal fans and journalists for a below-par display which was shaped by an early missed penalty.
Özil, the Gunners' £42.4m record signing, had earned himself a spot-kick early on in the first leg of the last-16 tie against the reigning European champions with a sumptuous piece of skill.
But, having tricked his way inside fellow German Jerome Boateng and subsequently being felled, his run-up was hesitant and his penalty poor, with Manuel Neuer able to make an easy stop to thwart a beleaguered-looking Özil.
His miss came at 0-0 when the Gunners were on top but he would fade badly for the remainder of the contest, with Bayern capitalising fully to seal a 2-0 win to take back to Munich for the return leg following Wojciech Szczesny's dismissal.
The 25-year-old has failed to hit the early heights of his Gunners career of late, suffering patricularly in the 5-1 drubbing at Liverpool, and took to his official Facebook page to apologise to fans for the defeat.
"The next morning doesn't feel better either. Sorry guys - it wasn't planned that way," he wrote. "Outnumbered it was really hard to win against this team."
Manager Arsene Wenger noted that his playmaker's head had visibly dropped after the penalty miss and spotted the German shaking his head after the incident.
"I think it affected Mesut," the Frenchman told reporters.
"He was still shaking his head five or 10 minutes after that. It had a huge impact on his performance. Confidence is your petrol in the team - it gives you the desire to play."
Are Arsenal fans right to criticise Mesut Özil's performance?
