Bayern Munich star Noussair Mazraoui is the latest defender to be linked with a summer transfer to Manchester United.
Sky Sports Germany's Florian Plettenburg revealed that the English giants are assessing a move for the Morocco international at present.
The 26-year-old is also a potential target for West Ham United.
The two Premier League clubs are set to battle it out for the former Ajax star, although Bayern want €20-25 million for him.
Manchester United are tempted to move for the Moroccan, but his price tag is seen as excessive.
Mazraoui, who is respected for his talent, is also extremely prone to injury.
