Roy Keane is certain Paul Pogba could perform at a higher level and that the Frenchman knows it himself.

Manchester United legend says good players must be self-critical if they play in a big club and fail to win a trophy.

Pogba is considered to be the most important player in Jose Mourinho side that came out empty-handed at the end of the season.

"He's a good player. Would he feel he could have had a better season? Probably," Keane said.

"Usually the good players are quite critical of themselves. When you play for Man United and you don't win a trophy you probably would be critical of yourself."
