United's Rooney, Rojo ruled out against West Ham

LONDON: Manchester United will be without captain Wayne Rooney and defender Marcos Rojo for their Premier League clash against West Ham United, manager Louis van Gaal said on Friday.

Rooney has been ruled out of Saturday's game at Old Trafford with an ankle injury he picked up in the 1-1 draw with Leicester City at the weekend, while fullback Rojo has suffered a repeat of the shoulder dislocation he had last season.

"Wayne's injury is more heavy than we thought and it's a nasty injury," Van Gaal told the club's website on Friday.

"When we go on it's been getting worse. We have to let him train to make the ankle stronger, that's very important.

"I cannot say (how long he'll be out) because the doctor shall decide that with Wayne of course. He is training well in the rehabilitation."

Van Gaal also confirmed that Rojo had dislocated his shoulder in training and bemoaned his luck at the string of "unavoidable" injuries his players had suffered.

"Rojo has been injured. It's his shoulder, the same as last year, in a training session. It's very unfortunate, also in the position of Luke Shaw so I have a great problem," he said.

"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."

Phil Jones (ankle/foot) and Ander Herrera (hamstring) are also ruled out against eighth-placed West Ham, but young midfielder Jesse Lingard (hamstring) is returning to fitness after missing the game against Leicester.
