Manchester United's Victor Lindelof (thigh) expected to miss a month

Jose Mourinho has told Manchester United's underachieving players to "stay at home" if they can not handle the pressure to perform at Old Trafford as they seek to reach the Champions League last 16.

"I want the team to start strong, go strong on the opposition, not to be waiting", he said.

"That's exactly what I want and probably you or the fans, they think "oh, Jose told them to start slow", "Jose told them to play nice and easy and wait to see what happens" or "to be losing for then to react". Do I prefer to play tomorrow at Young Boys here or go to Bern I would say immediately to play at home.

Before focusing on the clash against their Swiss opponents, Mourinho was asked in his press conference about the disappointing 0-0 draw at home against Crystal Palace on Saturday as his team are now seven points off the top four in the Premier League.

"I want to play this game as a knockout game and the team we are going to pick is a team that tries to have that happiness to cope with that little pressure to the players that is not a real pressure because the reality is we have one more match to play". I want to play this game like a knockout game, like we have to win.

Mourinho said defender Victor Lindelof would likely be out of action for "quite a while" with an injury.

"It's the biggest club in the world and we as players need to take what's said and take that on board. Let's play this game like a game we have to win".

The 23-year-old England left-back has started all of United's games in the Champions League this term.

Matteo Darmian, who started against Palace, was also missing from Monday's training, along with Marcos Rojo.

United have had problems getting to their home Champions League games on time this season and were hit with a UEFA fine after kickoff against Valencia was delayed by five minutes. "If it is not better I walk", Mourinho added.

"What he said the other day, that was more a generational thing", said Shaw.

"I think it would be a lack of respect to the stadium and the fans to say we prefer playing away", Mourinho said.

Speaking after the victory, United legend Scholes told BT Sport: 'I thought they were very bad, if they play against a half decent team they get beaten tonight.

"If you feel pressure where people come to support, stay and watch on TV".
