It could also spell the end of his time at Manchester United.
Man U midfielder Paul Pogba could miss the remainder of 2021 after injuring his thigh on international duty with France.
The French believe the 28-year-old will be out for between six and eight weeks, taking him to the end of the year.
That could bring about a quick exit from Manchester. Pogba is able to sign pre-contract terms with overseas clubs in the January transfer window - and his United contract runs out in June.
If he is out for eight weeks, he would miss two Champions League group games and up to 10 Premier League matches. The former Juventus midfielder was already going to miss United's next away match at Watford as a result of a three match domestic ban caused by his red card against Liverpool.
Pogba's absence will also put more pressure on Man U gaffer Ole Gunnar Solskjaer - who is already without a number of players because of injury. They include Raphael Varane, Edinson Cavani and Luke Shaw.
Swift Kicks Podcast has previously stated it is time for Pogba to leave Manchester United.
