The Manchester Evening News says United are prepared to sweat it out over Sneijder and make one final late swoop to land the Dutch playmaker.
The summer-long saga has been a roller-coaster with both Inter Milan and the Reds denying interest in selling or buying.
The Italians have dug their heels in yet again and president Massimo Moratti says: "Sneijder is going nowhere."
However, Sneijder is still said to be keen on a move to Old Trafford and there have been suggestions the £35m-rated 27-year-old would be prepared to drop his wage demands to make the transfer possible.
Meanwhile, United's coffers have been boosted by a £46.5m windfall from UEFA's Champions League prize and TV pot.
They earned even more from their Euro exploits last season than their Wembley final conquerors Barcelona due to United's small-screen popularity.
