on first defeat of the season…
Yes, we're really disappointed. We had a lot of possession with no real penetration. We could have played all day and we wouldn't have scored in the second half. I told them after the game that some of them seem to think they can just turn up and play - but they have got to work at it.

We went 1-0 up but then to be fair to West Brom they dominated us for 20 minutes. In the second half we've come out and I think they had one shot. But that's football.

When you play slowly and don't move the ball around quickly with no real determination to get in behind I think you'll get caught. You get punished and I think that's what has happened tonight.

on what went wrong…
It wasn't particularly disappointing but we’re looking at these players to develop and get into Arsenal's first-team squad. I said to them in the dressing room that it was a test against good players tonight and one or two have come up short. It's their careers and they have got to realise that. But we'll take it on the chin, bounce back and look forward to the next game.

on a positive start…

We started well and scored a good goal. We had a lot of possession but I thought West Brom played very well for 20 minutes and carved us open a few times. We made an individual error for their second but in truth I felt we were probably lucky to go in 2-1 down at half time.

on experience making the difference…
No, I don't think so. Wherever Roy Hodgson has been he's always used some experienced players at this level, and it’s good for our young players to see them working hard at their game. Being good professionals is what it is all about.

on Rhys Murphy's injury…

He's sustained a hamstring injury. I feel really sorry for Rhys because he's worked hard to get back and now the left [opposite side to previous injury] one has gone. That is football, we have got to find out what us causing that obviously and hopefully he'll return in a month to six weeks' time.
