Arsene Wenger has revealed that Wojciech Szczesny will miss 2-3 weeks because of injury, leaving the door open for Vito Mannone to continue his good form in goal.

The Italian stood in well for Szczesny in midweek, and against Liverpool and Stoke, and the ankle injury he picked up ahead of last weekend’s game against Southampton has ruled the Pole out for the next couple of weeks.

Other than that the squad which traveled to Montpellier is the one which will travel to Manchester on Sunday and Arsene Wenger is confident his team can get something from the game.

“If we’re at our best, we have a good chance to get a great result,” he said.

The boss also provided further info on the return of Jack Wilshere. The England international started full training again this week but the manager says he needs some football, in the shape of second-string games, before he can be considered for the first team again.

“Wilshere had ups and downs. He was focused, especially in the last three months. We have to be a bit cautious. When you’re so young and you’re out for 14 months, it’s a good test for your mental strength.

“We need to manage him well. He needs a few games in the reserves.”
