'My dream is to play for Manchester United in England,' Gattuso told the Mail on Sunday.
'I know it is a bit soon to talk about because we have this big game coming up against United, but I have always been fascinated by them. I would love to have a new experience, even in the next year or two. I would choose Manchester United ahead of Chelsea because the stadium has a very special atmosphere and the club is world famous, like Milan.'
'I have always been happy at Milan and I still am. But I think you need a new stimulus in your career. It is a question of the circumstances being right. When a club has been good to you, as Milan have been to me, and they say you are not for sale, it is difficult to know what you can do,' he added.
The former Rangers player is and admirer of Roy Keane and if SAF wants a reference then he need only turn to Walter Smith.
'I respect Keane because he has a similar game to mine and he is full of spirit. Above all, I like the way he leads. He has the stature at United that our own captain, Paolo Maldini, has at Milan.'
'I am sure Sir Alex knows all about me, because last year his assistant was Walter Smith, who had faith in me when I was young at Rangers.'
