Manchester United and Bayern Munich are eyeing Torino fullback Matteo Darmian.
The Daily Express says Darmian is rated at around £15m and Louis van Gaal has reportedly identified him as a target to fill the right back slot.
Van Gaal has used Antonio Valencia in recent weeks, although he is more accustomed to playing further forward.
Rafael has been absent for a lot of the season with injury but there have been rumours suggesting the Dutchman isn't keen on him.
