Alexis Sanchez could be out for up to six weeks with the torn hamstring he suffered in training for Manchester United.
Jose Mourinho believes Sanchez will miss the Christmas programme after pulling up in training on Thursday with what the United boss described as an ‘aggressive muscular injury’.
It is expected to keep him out for significantly longer than Victor Lindelof, who was sidelined for three weeks with a hamstring injury.
‘No scans yet but the player is experienced, the player knows what the injury is,’ said Mourinho.
‘Also from the top of my experience, just the painful scream and the way the injury happened I know it’s going to be for a long time.
‘It’s not the little muscular injury that in one week or 10 days the player is ready. It’s for me and also for Alexis, the feelings before the scans is that the grade is different than the (Victor) Lindelof one and the Lindelof one was not an easy one so Alexis has what I used to call an aggressive muscular injury.’
The United boss later added on MUTV: ‘From my experience, I would say he is not playing this year.’

Mourinho reiterated that he expects David de Gea to sign a new long-term contract at Old Trafford after United activated the 12-month extension on his current deal.
‘He wants to stay and I want him to stay, of course,’ added Mourinho. ‘He’s the level of player Manchester United needs. Manchester United needs the best players in the world. If we want to be Manchester United we need the best player in the world.
‘The manager wants him to stay, the board wants, David’s agent wants him to stay, he’s not the kind of agent that is manipulative like others, his agent lets him think and decide by himself so the point is to agree the contract and that’s just my feeling, they are going to finish well.’
Mourinho paid tribute to Marouane Fellaini whose injury-time winner against Young Boys sent United into the last 16 of the Champions League on Tuesday night.
