Sneijder is expected to agree on the bumper contract that would eclipse Wayne Rooney's [ Images ] 220,000 pound a week deal.
Inter Milan have, however, denied claims that Sneijder is planning to leave the club and join United.

Rooney excited over dawning of new era at Manchester United
Meanwhile, ace striker Wayne Rooney is excited over the dawning of a new era at Manchester United this summer.
United is all set to fly to America today for a three-week pre-season tour of Boston, Seattle, Chicago, New York and Washington.
With Paul Scholes, Gary Neville [ Images ] and Edwin van der Sar [ Images ] retiring, and Wes Brown [ Images ] and John O'Shea having joined Sunderland, Sir Alex Ferguson has overseen a significant overhaul of his squad, The Mirror reports.
"It's obviously sad to lose all those players from the dressing room. On the other hand, it's exciting having new players coming in. You want to see how the new players get on in training and in games so it's certainly exciting as well," said Rooney.
"Brown and O'Shea are ambitious footballers and want to play every week, so I understand why they have left but I'm sad to lose them as players and friends as well.
"It's certainly going to be a loss for us but they'll be excited to start a new life at Sunderland," Rooney added.
