Edwin van der Saar 
(Fulham)
Price: £5 million or less
Availability: The experienced Dutch international 'keeper has fallen in and out of favour at Craven Cottage under Chris Coleman and would like to seal a dream move to Old Trafford. However, the Dutchman's contract expires in the summer so Fulham may want to cash in whilst they can.
Likelihood: Likely.

Steven Gerrard 
(Liverpool)
Price: £30 - 40 million
Availability: Gerrard has candidly spoken out about his desire to be winning trophies year in year out, and the England international midfield can certainly do that as a Red Devil. Chelsea have also been tracking Gerrard and and certainly beat United in a transfer auction.
Likelihood: Very unlikely.

Edu
(Arsenal)
Price: £4 million
Availability: The Brazilian's contract expires quite soon and wants a more permanent role in the Gunners side. "It doesn't make me worried to play in England for another club," Edu recently revealed.
Likelihood: Likely.

Owen Hargreaves 
(Bayern Munich)
Price: £6 million
Availability: England international Hargreaves has been itching to play in the Premiership after an upsetting season of criticism last term in Germany. Hargreaves was close to moving to Spurs in the summer and may force a bidding war with United in January.
Likelihood: Quite Likely.
