Former Manchester United striker Dimitar Berbatov says he's a fan of Anthony Martial.
Berbatov is urging United not to sell the Frenchman.
He told Betfair: Everyone knows that he's not working the way he should be. He's not using his quality properly and he's struggling because of this. He needs to be shaken up a little bit and there are moments where he needs to push hard and change his game.
He needs to do something extra. When you've been at a club for a long time, you get complacent. From time to time, you need to challenge yourself and the people around you need to wake you up and say, 'look, you have so many qualities that you're not using correctly.
"Wake up, do more and bring it to the team'."
