Sneijder was heavily linked with a move to United during the transfer window.
“If somebody asks me if I will ever play for Manchester United, it’s impossible for me to say no,” Sneijder told the Daily Star Sunday.
“How can you say that if the chance came you would not play for one of the biggest clubs in the world?
“I don’t think there is any player in the world who could publicly rule out ever playing for Manchester United, and if they did I would doubt they were telling the truth.”
He added: “The Premier League, in terms of top clubs, is the strongest in the world, and it would be nice to finish my career saying I have played at the very top in Spain, Italy, and England.
“There is not many who can say they have done that, and if that does happen for me I would only want it to be with Manchester United.”
