The Manchester Evening News says Germany No1 Manuel Neuer is Fergie's top target.
Bayern Munich legend Oliver Kahn believes Neuer can become the best in the world at a club the size of United's.
United have signed £3.5m Dane Anders Lindegaard from Norwegian club Aalesunds and he has begun training at Carrington but is ineligible to play until after January 4.
But Lindegaard looks likely to step into Tomasz Kuszczak’s boots as deputy with the Pole set to leave in the summer as well.
Now the emphasis is bringing in internationals of the calibre of Neuer, Lyon’s French number one Hugo Loris or Ajax’s Dutch first choice Maarten Stekelenburg.
