Former England goalkeeper Paul Robinson says Everton defender Michael Keane needs to sharpen up his game.

Robinson highlighted one key aspect his ex-teammate still needs to improve.

"I played with him at Burnley and saw him obviously younger than he is now," he remarked.

"He's an all-round centre half, but I think one thing he lacks ever so slightly is concentration. He needs somebody next to him to keep him on the ball all the time, if you like.

"His ability as a footballer, his passing ability, is unquestioned - his ability in the air, and he's got so much speed. He sometimes get caught out, people get in behind him but he's deceptively quick and gets back and covers very, very well."
