The Dutchman, now with Turkish club Galatasaray, was heavily linked with United back in 2010 but has revealed that the Nerazzurri did not want him to depart after they took out the treble in the 2009/10 season.
"We had some talks with Alex Ferguson back in 2010,” Sneijder said.
"They [United] contacted the club after our Treble season but too much money was asked for. And I was also happy at Inter so I decided to stay.
"Manchester United are a fantastic club and they kept showing interest after that year but not as determined as before.
"I don't give much thought about proposed transfers, if I'm happy somewhere, I'm happy there."
