and are set to battle for the signature of AS Monaco midfielder Youri Tielemans, according to reports.
The 21-year-old is playing in his second season for Monaco having joined from Anderlecht in 2017 for a fee of around £21.6 million.
And according to Belgian newspaper , the return of Leonardo Jardim in the dugout at the Stade Louis II has opened up the possibility of Tielemans leaving after less than two years at the club.
He’s one of few players to have a satisfactory season so far at the Ligue 1 side, having scored five goals in a dismal campaign which sees them currently in 19th place.
However, while his club has endured a poor season, Tieleman impressed at last year’s World Cup for Belgium where he made four appearances.
This has attracted the attention of United and Barca, while 2015/16 Premier League champions Leicester City are also said to be interested.
As reported by , the Foxes are also currently in talks with Monaco over a potential £20 million switch to the Premier League.
But it remains to be seen if Leicester have enough to lure the Belgian to the King Power Stadium while United and Barca loom over a potential transfer themselves.
The transfer window closes on January 31 with the Red Devils yet to make a signing this month, while Barcelona have brought in Kevin-Prince Boateng.
