Arsene Wenger admits that his Arsenal side collapsed in the second half of their 5-1 defeat to Bayern Munich at Allianz Arena on Wednesday.
The hosts took the lead through Arjen Robben but the Gunners hit back through Alexis Sanchez and went into half-time with the game level at 1-1.
Arsenal lost Laurent Koscielny to injury shortly after the break and two quick goals from Robert Lewandowski and Thiago gave the visitors a mountain to climb.
Thiago then added a second before a late Thomas Muller goal left Arsenal’s hopes in tatters and Wenger admits his side fell apart in the second half.
“The most important thing in the second half was we lost Koscielny very quickly, he came off at 1-1,” Wenger said via Standard Sport. “Suddenly it looked that we collapsed. It’s difficult mentally.
“I do not look for excuses. It’s an explanation because we looked quite solid defensively and after that.
“It’s very difficult just after a game, it’s a shock of course to lose at that level. On top of that we made everything wrong, the fifth goal shows that.”
Arsenal now look destined to exit the Champions League at the last 16 stage for the seventh consecutive season and Wenger admits Bayern fully deserved their victory.
“Overall I must say they’re a better team than us,” he added. “They played very well in the second half and we dropped our level. We were a bit unlucky as well but overall well done Bayern, they were better than us.”
The Gunners now head back to England and must pick themselves up quickly as they face a potentially tricky test against Sutton United in the FA Cup fifth round on Monday night.
