Former Manchester United academy coach Paul McGuinness says they should re-sign Michael Keane from Burnley.

United let the defender leave for just £2.5million in 2015 when Louis van Gaal was in charge.

Liverpool, Chelsea and Manchester City are all watching Keane's progress closely.

But McGuinness reckons the Red Devils should look to take Keane back to Old Trafford as he is better than Mats Hummels.

“He's quicker, better in the air and decent with his feet. He's not as experienced as Hummels but he knows the club, he's a United player really in that sense, so he'd tick a lot of boxes," McGuinness said. “He has the potential to be a really top player. He's smoother on the ball or at least as good as the central defenders United have at the moment, so of course he could [be successful]."
