Alexis Sanchez is very demanding and difficult to manage at Arsenal, says Martin Keown

Martin Keown has claimed Alexis Sanchez as "difficult to manage" and "very demanding" at Arsenal.

Arsenal have endured a difficult season, finishing fifth in the Premier League table and yet another round-of-16 exit from the Champions League by Bayern Munich.

Having scored 24 goals and assisted 10 this season, Sanchez has been the standout performer for the Gunners despite a string of on-pitch disappointments in north London and increased pressure on Arsene Wenger.

Although the ex-Barcelona man is a fan favourite, former Arsenal defender Keown says Sanchez is "demanding" behind the scenes.

He said: “I think he's a difficult man to manage.

“I did turn up at the training ground once - and it was one of his days off but he suddenly turned up and he was bouncing around the training pitch.”

“They were having to facilitate him and put a training session on for him. That can be a good thing but he's a very demanding individual.”
