Arsenal manager Arsene Wenger fears his star player Alexis Sanchez will not get adequate rest during the summer break as he deals with Copa America obligations.

The Chilean was a constant presence in Arsenal's starting eleven during the recently-completed Premier League season and will aim to take hosts Chile all the way to the final of South America's top tournament Santiago on July 4.

"I feel this competition is a bit too much. I will watch it, but with a little bit of fear because Sanchez has played 50 games for us and goes there again, having already played in the World Cup last summer," said the Arsenal boss.

"I am really surprised that FIFA authorised that. It is disappointing that they speak a lot about the health of the players, but when you look at the competition that is organised, this Copa America, and look at the date of the start of the Premier League, it is not reasonable."
