Manchester United must keep ahold of David De Gea to achieve success, winger Jesse Lingard has claimed.

De Gea made 11 saves in Sunday's 1-0 win over Tottenham Hotspur.

United have triggered a clause that will keep De Gea for another season, but Lingard thinks he deserves a long-term deal.

"He's one of the best keepers in the world, if not the best," Lingard said.

"We want him to stay. Having a keeper like that gives you extra confidence. He's a great goalkeeper."
