Arsenal boss Arsene Wenger is demanding a big performance from Alexis Sanchez for Sunday's clash with Manchester City.
Wenger doesn't doubt Alexis' commitment going into the game, despite his wish to join Cty.
He said: “When you are a football player, you have a social contract with the rest of the team and I never question that.
“Once you don't respect that, it's difficult to say that you play football."
Wenger added: “I think he's coming back stronger physically. He runs after a goal at the moment so he's a bit frustrated when he doesn't score, like all goalscorers.
“I'm not worried about it. He works hard and it will come back quickly. You can never try too hard.
"At the moment he's marked well, they double up on him, but he still creates many dangerous situations and the goal, he just has not to worry too much.
“I know you always say that to strikers and they still worry but over a longer period he has always scored and that will come back."
