Manchester United is reportedly after the services of Monaco defender Fode Ballo-Toure according to journalist Duncan Castles.
According to Castles, the 20-time English champions are currently tracking the former France Under-21 international, who has a contract with Robert Moreno's team until June 2023.
"The player that Man United are looking at is Fode Ballo-Toure. He's a 23-year-old left-back. He is an exceptionally quick, very powerful player, physically has lots of stamina, and strikes me as having a very good profile for English football from a physical perspective," Castles told the Transfer Window Podcast.
"Also, I'm told he's an excellent character, so there's belief that he would transfer well from the French game to the English game and not have as long an adaptation process as some players do when they switch countries."
Chelsea is also believed to be weighing up a summer approach.
The 23-year-old came through the youth system at Paris Saint-Germain but did not make a first-team appearance for the capital giants before joining Lille in 2017.
