Manchester United's depleted options at full-back have taken another blow, following confirmation that Matteo Darmian has suffered a dislocated shoulder. Darmian, 26, lasted just 37 minutes in Saturday's 2-1 defeat Sunderland at the Stadium Light after a heavy collision with Wahbi Khazri.

The Italy international was replaced by United youngster Donald Love and is now set for another spell out of the club's first team.

"Unfortunately, Darmian is a dislocation and he's out for several weeks," United boss Louis van Gaal said. "We don't have any more full-backs."

Van Gaal has been forced to change his back four throughout the season with his options at both right-back and left-back suffering from a string of injury problems. Luke Shaw remains a long-term absentee after his double leg break in September while Antonio Valencia and Marcos are yet to play a game in 2016.

Ashley Young has been used in both positions as a result but the 30-year-old is also ruled out with what his manager described as a "severe" groin injury suffered in January. Youngsters Guillermo Varela and Cameron Borthwick-Jackson have taken their chances in the first-team given the absences of senior players, but the former is also currently carrying a knock suffered while playing for the club's Under-21 ranks on Monday.

Rojo has also been out with a shoulder injury while Valencia was forced to undergo foot injury in November but van Gaal is hopeful of having the South American duo back soon.

"The light at the end of the tunnel is more for Rojo and for Valencia," van Gaal told a press conference on Friday. "They are coming back and I hope it's as soon as possible."

The club's injuries are not just limited to their full-backs, however. Phil Jones suffered another setback on Monday while playing for the Under-21s, a game in which Adnan Januzaj was forced off with a knock of his own/

Bastian Schweinsteiger has not played since picking up a knee injury in the FA Cup third round victory over Sheffield United and has been given a short break by his manager to speed up his recovery.

United begin their Europa League campaign against FC Midtjylland on Thursday, 18 February, before taking on Shrewsbury Town in their FA Cup fifth round clash on Monday, 22 February.
