Alexis Sánchez’s workload is taking a visible toll as he's played in nearly every match for Arsenal following a taxing World Cup, according to Arsène Wenger.

“He is in the red zone,” Wenger said. “You can see that when he plays but he can dig deep. He played his 27th game on Wednesday since the start of the season, if you consider international games and travelling on top of that. Unfortunately you never know how far you can push it. We are not scientific enough to predict that completely but he has good recovery potential. He recovers very quickly.”
