Arsenal legend Patrick Vieira feels they need to sell Alexis Sanchez.

Arsenal have been trying to tie down Sanchez and Mesut Ozil to the club for nearly 18 months but have been met with resistance.

And they are now facing the prospect of losing the pair for free next summer along with the likes of Jack Wilshere.

Vieira, who won six trophies with Arsenal, believes that if a player wants to leave, he should be let go.

He told Copa 90: “When a player wants to leave a football club, I think they should let him go.

“When a player doesn't want to stay at a football club any more, he's never going to give 100 per cent and he is never going to give you his best.

“And I believe when a player wants to leave the club, you should let him go because there is no player bigger than the club."
