Arsene Wenger conceded he is in a "very difficult situation" after Arsenal's wretched campaign hit a new low with a humiliating Champions League exit against Bayern Munich.

Wenger's side suffered their heaviest home defeat for 19 years as Bayern romped to a 5-1 victory on Tuesday that sealed a 10-2 aggregate success in the last 16 tie.

It was an evening of abject misery for Wenger, who was subjected to calls for his resignation from Arsenal fans before and after one of the most chastening losses of his 21-year reign.

Wenger angrily complained that refereeing decisions had denied his team the chance of an epic fightback after Theo Walcott's opener was cancelled out by a Robert Lewandowski penalty that led to the dismissal of Gunners defender Laurent Koscielny.

Asked if he would be managing Arsenal in Europe next season, Wenger, who has yet to reveal if he will extend his contract when it expires at the end of the campaign, gave a response that invited renewed speculation about his future.

"I don't know, you always want headlines. I'm here to speak about football not my future," he said.

“I don't feel there was any uncertainty from the players. We played very well. At the moment we are going through a very difficult situation, but I think this club is in great shape."
