Manchester United are lacking options in their backline after Marcos Rojo has been ruled out of the upcoming match against Sunderland, according to reports from the Daily Mail.
The 25-year-old picked up an injury to his hamstring during the 3-2 victory over Southampton last weekend and missed the 3-0 midweek win over Ipswich in the Capital One Cup.
Paddy McNair, who came on as a late substitute in the match against the Saints, also picked up an injury and is likely to be out of contention against the Black Cats.
Manager Louis van Gaal is now frustrated that he is without two natural left-backs following the injury to Rojo as well as Luke Shaw, who could miss up to nine months following his leg break.
Ashley Young played at left-back in midweek with versatile midfielder Daley Blind likely to retain his role at centre-back alongside Chris Smalling.
There is also the option of switching summer signing Matteo Darmian onto the left flank while allowing Antonio Valencia to slot in at right-back.
