Burnley goalkeeper Tom Heaton has no doubts about the quality of Michael Keane.
Keane, who recently made his move to Burnley permanent, is a graduate of the Manchester United youth system along with David Jones and Heaton.
Heaton told the Lancashire Evening Telegraph: "I've enjoyed playing with Keano since he came into the team.
"I think a centre half playing in the Premier League at 21 or 22, I don't think there's too many of those about, so fair play to him.
"The sky's the limit for him. Obviously his size is important, he's quick, he's good on the ball, he's good in the air, what else do you need?
"He has another side to him as well. He can tackle, he can head it, he can put the blocks in, so if he can mix the two sides to his game and find the balance he can be an outstanding player.
"He has got an awful lot about him and a lot more to come.
"He's a very good signing for us."
