If you play three at the back who are all playing out of position how can you expect any coherent defending? - obvious really, but apparently not to Mr.Wenger, who continues with his strange team selections.
He said after the game:
"Last week we conceded two goals on corners and they only had three shots on goal, so I don't believe we defended so badly.
"But here I say we could look at ourselves and, on the goal we conceded, we were 100 per cent guilty.
"We are very frustrated because we lost a game that we should have won and that's terrible to swallow.
"We had plenty of chances and on top of that, not only did we not finish, but we gave them an easy goal to score, just after half-time.
"We knew at half-time it was very important to keep our defensive focus in this kind of game, then we came out and didn't defend properly. That's where we are not forgivable today."
"At the end of the day I believe when you are not concentrating on the way you want to play, you pay for it at that level," he said.
"In the Premier League you do not get away with defending like we did on the goal.
"We have to realise as well, that if we want to transform the energy we put into the game as well like that, you have to defend properly, every single minute.
"But it is vital to not only see the negative side of it and to respond very quickly in the next game."
