Arsenal lost to Watford 2-1 to fall nine points behind Manchester City after eight matches.

Arsene Wenger admitted it will be difficult for Arsenal to get back into the Premier League title race.

"It will be difficult [to catch the leaders], of course. But I think at the moment we are not too much looking at Man City, we are looking at ourselves," Wenger told a news conference.

"We have to bounce back from our disappointment today because we look like we can make results when we play the game like we did in the first half. But we need to be at the level for 90 minutes like that."
