It's about the Portuguese top team's relatively young, 39-year-old, coach Rúben Amorim. United are said to be in contact with Amorim in the hunt for a replacement for Erik ten Hag, who was fired on Monday after United's less successful season start.
Sky Sports reports that the Premier League giant is said to be willing to buy out the Portuguese coach.
At a press conference on Monday, Amorim said he expects to be asked about the job at Manchester but didn't want to say more than that.
Amorim has previously been linked to Liverpool after Jürgen Klopp left the club, but in the end, Liverpool chose the Dutchman Arne Slot as their new head coach.
While waiting for a long-term successor, ten Hag's assistant coach Ruud van Nistelroy has temporarily taken over as United coach.
