Former Arsenal star Paul Merson has warned Manchester United against selling Wayne Rooney.

Merson wrote in the Daily Star: "Wayne Rooney is the kind of fella who can come back to haunt you in a big way.

"That's why Manchester United would be making a big mistake to offload him in the summer.

"They wouldn't sell him to a Premier League rival - they would want him out of sight abroad.

"But if he went to the continent, you wouldn't bet against him going back to Old Trafford one day and making them suffer even more Champions League heartbreak."
