Tampa Bay Buccaneers quarter-back Ronde Barber admits he's Manchester United mad and a big fan of Wayne Rooney.
Barber is gearing up to take on New England Patriots at Wembley tomorrow.
But he will be sure to keep an eye on events at Anfield, where his favourite football team United take on Liverpool.
He said: "My favourite United player was Cristiano Ronaldo, until he left the club. Now I dislike him like every other Man U fan.
"I like Wayne Rooney. He has that demeanour, a brute quality that means he could adapt to our game.
"I think he'd make a great running-back, somebody who runs the ball. He has got a lot of skill."
