What I’m praying is that after the international break we have the team fully physically equipped.READ MORE IN FOOTBALL“That they are available and that they are fit, because it’s been a nightmare for eight weeks.“Doubt after doubt, issue after issue, not only with the ones that are not able to play, but with the ones who are able to play only for certain moments and not able to play.“So I’m just asking that, because the desire the team has and how much we want it there’s no question. It’s going to come. We just need that on our side to be more consistent.“When it gets nasty, show your teeth and show how much you want it.Most read in FootballAs Arsenal’s form dips through injuries, Arteta himself took a slide, as he fell over in despair after a last-gasp Leandro Trossard missCredit: ReutersFOOTBALL FREE BETS AND SIGN UP DEALS”When it’s Disneyland it’s very easy.

That’s nowhere near the standards of our defensive habits, how we allowed it.“The moment you give space and time to any of their players with the quality that they have you’re going to get punished, so that’s not bad luck.“That’s not very much like us. I think today in that sense with the way we conceded, we have to fault ourselves. “That’s something that we have to do better, especially when you’re not scoring two or three goals and, at the moment, we are not.“I’m disappointed with the result because I think we deserved more. And at the same time very proud of the team for the way we played against this opponent in this stadium.“Chelsea have battered everyone here and it wasn’t the case today.“After their goal the team showed its teeth. We took risks, we were very aggressive, we created three big chances.
