The Premier League champions have been repeatedly linked with the 27-year-old Dutch international as a replacement for the recently-retired Paul Scholes.
"Are Manchester United still after Sneijder? We haven't seen or heard from anyone; that's a story I've heard from you," Paolillo told Sky Sport Italia.
However, the Inter official did hint that the player could leave at the right price.
"Is Wesley definitely not for sale? I don't think there's anything that can't be sold, it all depends on the price," he added.
