Manchester United are assessing whether to pursue Monaco pair Vanderson and Youssof Fofana.
The Red Devils have concerns in more than one area of their squad so far this season.
Per Give Me Sport, Vanderson and Fofana are two players that United boss Erik ten Hag admires.
Vanderson is a right-back who would replace either Diogo Dalot or Aaron Wan-Bissaka at United.
Fofana is a defensive midfielder who could come in as a Casemiro replacement.
