However, the former Manchester United player is rumoured to be high of Harry Redknapp’s summer wish list.

Richardson has revitalised his career that once showed such promise and earned him a handful of England appearances.

Redknapp is believed to be a fan of his versatility with his ability to play across the midfield of as a left wing-back, although Sunderland will be anxious to shake off the suggestion they are a selling club after Darren Bent’s departure in January.

Richardson would cost Spurs in the region of £9m.

Spurs travel to the San Siro with doubts over Bale, Luka Modric, Rafael van der Vaart and with Tom Huddlestone on the bench, leaving Harry Redknapp’s task even harder than it already was.

Harry Redknapp told SkySports today that Bale will more than likely miss out after inconsistent stories on Bale’s health in the Sunday papers.

He said: “He’s struggling, to be truthful. I’d like to be able to scare Milan a bit and say he’s going to be available but he’s struggling to get over this back injury.”

He added: “The specialists don’t see too much of a problem that should keep him out too long.

“(But) we’re going to make sure he’s right. He’s a young lad and got a great future in front of him. We couldn’t take a chance. He doesn’t feel he’s ready to play. We’ll leave it to him.

“He came up yesterday (Saturday) when we were at Sunderland and worked with the fitness coaches. When they started to push him a bit he couldn’t go on and didn’t feel right so they had to go back a few steps and start again.”
