Sporting president Frederico Varandas and United executive vice-chairman Ed Woodward were present at a meeting at the club's Mayfair offices on Friday with discussions set to continue this week.
The priority for Manchester United is the signing of a quality midfielder in the current January transfer window and it seems they have identified Sporting Lisbon skipper Bruno Fernandes as the man to boost their squad in the area of the need.
United see free-scoring midfielder Fernandes as the ideal player to bolster their ailing midfield, with Paul Pogba and Scott McTominay both out injured.
Sky Sports News has been told United are prepared to let Argentine defender Rojo leave Old Trafford. "United is a club that Bruno Fernandes likes very much in England, it is a club he really wants to play for".
Bruno Fernandes has been in terrific form over the last few seasons since joining Sporting in 2017.
Fernandes primary role in midfield is at number 10 position and Manchester United doesn't have anyone reliable to play over there. I hope it doesn't happen, but we have to start thinking that.
As per ESPN, Bruno Fernandes now earns around £65,000 per week at Sporting Lisbon but once he moves to Man United, the player is expected to get a massive pay rise. We do have backing to do something if the right thing comes up in this window. We are building towards something, I'm nearly getting bored myself talking about what we do have as a vision and a plan. Add in the five goals and three assists he put together in five Europa League group stage games this season, including two goals and two assists in the 4-0 annihilation of PSV in November - a win that secured Sporting's place in the knockout rounds - and you clearly have a player who has mastered the level he is now playing at.
