"He felt his knee on the second goal so we decided to change".

Unfortunately, feeling his knee does not excuse the error, as it was Wrighty's arms which failed to make the movement towards the ball which might have kept it out.

But we'll have to trust Le Boss as far as the substitution is concerned. He went on to say that he doesn't know yet if the injury is enough to keep Wright out of the Man Utd match on Sunday.

Does that perhaps suggest that it might not have been so bad that Wright could not have carried on if necessary? That a loss of confidence was a factor in his substitution?

What if we had no keeper on the bench, would Wright have been able to carry on then? How far different was the situation Arsenal facd at half-time, when the alternative to Wright was a young keeper with next to no experience?

Arsenal fans will be asking themselves these questions tonight, but we like to think that the fact that Taylor was brought on is indicative less of a loss of confidence in Wright (on the part, possibly, of Wright himself as well as the manager) than of a high level of confidence in the rookie Taylor.

See Guardian for more post-match quotes.

Later quotes from Wenger show that he's big enough to shoulder the blame himself.

"It was the wrong decision to pick Richard because he didn’t feel right before the game and should not have played in the circumstances. I thought he would be okay but their second goal was down to his knee injury and now there is a chance he will miss Sunday’s match against Manchester United."

Healso reflectes further on Arsenal's away form, "We do not have enough self belief away from home and because of that, we are starting apprehensively".

The thing that's baffling Arsenal fans is the fact that in the Premiership it's the exact opposite. We're doing better away from home. But arguably it's the same cause. In other words, in the Premiership we're suffering at home because of over-confidence.
