Manchester United are in the market for at least two new signings in the January transfer window.

Louis van Gaal has revealed that he wants to strengthen his squad after Wayne Rooney and Marcos Rojo joined the United casualty list this week.

Both players will miss United’s Premier League clash against West Ham at Old Trafford on Saturday and the must-win Champions League showdown against Wolfsburg in Germany next week.

Rooney has begun his rehabilitation after suffering what the manager revealed was a “nasty” ankle injury while Rojo dislocated his shoulder in training on Wednesday and may require surgery.

Van Gaal is concerned at the team’s growing injury list, which includes Phil Jones and Ander Herrera, as well as long-term absentees Luke Shaw and Antonio Valencia.

Speaking at his media conference on Friday afternoon, Van Gaal said: “We are looking [to sign players], but as you know it is not so easy to buy players and in January it is more difficult. We are looking but it is not for sure.”

The United manager is aware that he has to carefully manage the workloads of his players, with the hectic festive period coming up.

“The week after next we have two weeks that we can have more recovery,” Van Gaal explained. “I have already given the players two days off this week. I am giving them a lot of rest because I think it is necessary now, nevertheless we have six injuries most of which are contact injuries.

“You cannot avoid those because football is a sport with direct resistance. We are unlucky I have to say.”
