Mikel Arteta says Arsenal's victory at Bayern Munich cannot patch over their weaknesses.

The midfielder says critics are right to pile on.

Arteta said: "Some of the critics are right, you know.

"When you concede three goals at home [against Bayern Munich] you can't expect anything different. The way we conceded the goals against Spurs, when we were dominating the game, and you end up losing the game. It's frustrating.

"We put some things right tonight. To get a clean sheet here is very, very difficult. You look at the stars they've got here. They're probably the best team in Europe."
