Arsenal manager Arsene Wenger insists that while Alexis Sanchez has not signed a new contract with them, he will still back him up to find his form.
Sanchez has still not given his best form this season as he has only scored one goal and two assists in seven Premier League games.
The Chile international is rumoured to be moving to Manchester City in January which some doubt if he would do his best during the game.
“I think he’s coming back stronger physically,” the Frenchman told UK newspapers.
“He runs after goals at the moment so he’s a bit frustrated when he doesn’t score, like all the goalscorers. I’m not worried about it, he works hard and that 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.
“He needs to not worry too much. I know when you say that to the strikers they still worry but on a longer period he has always scored goals. That will come back.”
Wenger said he is not worried about Sanchez as he is still craving for wins.
“I am not concerned. I am not suspicious of the performances or the desire to win of a football player,” he said.
“When you are a 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.”
