Marcos Rojo, who has been sidelined since December by a dislocated shoulder, has returned to Argentina to continue his rehabilitation. The Manchester United defender suffered the injury during training at the end of last year and is not penciled in for a return anytime soon.

The Argentina Football Association (AFA) confirmed his return to Buenos Aires on their official Twitter account alongside a picture of Rojo in the gym. This is the second time the defender has injured the same shoulder. The earlier injury came during the derby against Manchester City in November during the 2014/15 campaign.

"Marcos Rojo spent yesterday in the grounds of the AFA to continue rehabilitating," the AFA posted on their official Twitter account on Wednesday (27 January).

Louis van Gaal is facing a major injury crisis in his defensive department, especially in the full-back position, as all his first choice players are currently out injured. Left-backs Luke Shaw and Rojo are out injured, with the former ruled out for the rest of the season with a multiple fracture in his leg, while the latter is a long-term absentee as well.

On the opposite side, Antonio Valencia is a long-term casualty after undergoing surgery for a foot injury, while Matteo Darmian suffered a head injury during their 1-0 loss to Southampton on Saturday (23 January). Darmian is expected to be back shortly.

The Dutch manager has admitted that the 20-time English champions are looking to sign a full-back as he currently only has youth team players Cameron Bortwick-Jackson and Guillermo Varela to cover for the injured stars. Ashley Young, who has been used as a back-up in both full-back positions recently suffered a severe groin injury, which is likely to keep him out for at least six weeks.
