Neto has stood out in victories over Crystal Palace and Southampton since the turn of the year, while causing Chelsea all sorts of problems in a 2-1 win over Chelsea back in December.
And his development suggests United would be onto a winner if they were to bring him to Old Trafford at the end of the season.
If Neto does arrive, he could even follow in the same footsteps as compatriots Ronaldo, Nani and Fernandes.
United signed Ronaldo from Sporting Lisbon back in the summer of 2003 as David Beckham’s replacement, landing him after he blitzed them in a pre-season friendly.
And the Portugal international recovered from a shaky start to become a huge hit, propelling the club to three Premier League titles on the spin under Sir Alex Ferguson.
