The 29-year-old would like to play alongside Wayne Rooney at Old Trafford and is not interested in a move to Tottenham, who have recently been linked with a move for him.
Fabiano told the Daily Star Sunday: “I have a real chance of winning a World Cup here in South Africa, and that is what I must stay focused on even though I know my future has to be sorted soon.
“I have made it clear that I will not be signing a new contract with Sevilla and at 29 I now need to join a club where I can start challenging for the highest honours from the first season.
“I have heard Tottenham Hotspur made an inquiry about me but, with all respect, that is not somewhere I am going to be able to win the Premier League or the European Cup in the next three or four years.
“There would be no point in me joining Tottenham. I might as well stay at Sevilla, as it’s the same thing. Sevilla are actually bigger when you look at how much we have been in the European Cup, so there would be no point me moving to a smaller team.
“The choice will come down to Manchester United and AC Milan. That is the sort of team I want to be signing for, one of the true giants of Europe.
“I think the way Manchester United play football is very attractive, I must be honest and say Premier League football attracts me and also the way Manchester United play football attracts me.
“You think about being Wayne Rooney’s strike partner and that is very attractive for any striker.
“I think the style of Premier League football suits me and I think I could score goals and be very successful there.
“Their coach is a winner, their players are winners and they are one of the few teams in Europe challenging for the top honours season after season.
“As soon as the World Cup is over I will make a quick decision on my future – and while it is going on I hope Sevilla can open discussions. I have enjoyed my time here but I now need to be at a giant.”
