Manchester United forward Alexis Sanchez will remain on the sidelines for a "long time" says, Jose Mourinho.
The Chilean international sustained a hamstring injury in training on Thursday and is set to be out for over a month.
The 29-year-old is yet to have a scan to determine the extent of the damage but Mourinho said he was "screaming" in pain.

"It is not a little muscular injury from which he will be ready in a week or 10 days. It is an aggressive muscular injury. He has not had a scan yet but the player is experienced. He knows what the injury is."
"From my experience, the painful scream and the way it happened, it will be a long time." Jose Mourinho concluded.
Sanchez has started just seven games so far this season in a campaign that has been plagued by injuries.
