Manchester United are reportedly keeping a close eye on Antonio Rudiger's situation at Chelsea, with the Red Devils eyeing a move for the centre-back this summer.
The Germany international's contract at Stamford Bridge is due to expire at the end of June, and he has allegedly turned down his club's latest offer.
As it stands, Rudiger will be available on a free transfer at the end of June, and both Real Madrid and Paris Saint-Germain are said to be firmly in the hunt for his signature.
However, according to the Daily Mail, there is also serious interest from Man United, with the 20-time English champions 'watching developments closely' ahead of a possible dramatic move.
The 28-year-old has been in impressive form for Chelsea during the 2021-22 campaign, scoring three times and providing four assists in 23 appearances in all competitions.
Man United are thought to be keen to add a new centre-back to their squad this summer, with Phil Jones and Eric Bailly potentially both moving on ahead of next season.
