Arsène Wenger believes that the “hyperactive” Alexis Sanchez will get even better this season.
The Chilean international enjoyed a fine debut campaign in England, scoring 25 goals as the Gunners finished third and won the FA Cup.
However, Wenger says he is ready for action once again.
“He came back reasonably fit,” the manager said on the Arsenal website.
“He practised for two weeks before he came back. He did not start from zero. In training now, he looks alright.
“I knew before the start that, once he was here, he would be difficult to stop. So I gave him a long enough break. He had four weeks off, which is quite reasonable. He finished on July 3 and he came back on August 3.
“He works extremely hard in every single training session to show that he is ready. I think what he does is, for me, normal. It is what everybody should do. You wonder if he has created a beach at home, and runs along the living room! He is a hyperactive guy. He needs that to be happy.
“He played 52 or 53 games last season, plus the Copa America. That means somewhere he has an instinct that shows how far he can go. It is difficult. In March, April, May, you could see he was a bit jaded. But he is still a guy who can make a decision in a game. And once he is out there he gives 100 per cent.”
