The Sun says United are set to sign £60million sensation Fernandes by the end of the week.
The goalscoring midfielder, 25, is expected to agree a five-year contract worth around £100,000 a week.
Officials from both clubs met in London to thrash out a deal and the Sporting representatives have flown back to finalise the move.
Portugal star Fernandes signed a new deal at Sporting just SIX WEEKS ago — but sources felt he was still likely to leave.
He should provide United with a much-needed creative spark, as well as chipping in with plenty of goals himself.
He's scored 15 times and provided 13 assists for Sporting in 25 matches so far this season.
