Manchester United Double winner Andrei Shevchenko says they must fight to keep David de Gea.

De Gea is expected to move to Real Madrid this summer.

Speaking to talkSPORT, the former United winger said: “After Peter Schmeichel, David de Gea is the best goalkeeper in Manchester United's history.

“For me, it's Peter Schmeichel number one, David de Gea number two. He's one of the best they've ever had.

“If De Gea left, Manchester United would have a big, big problem.

“He's an excellent goalkeeper. He plays a huge role for the team and the defence."
