The Manchester United boss does not see the Champions League clash to be crucial. The Red Devils will host the Switzerland outfit at Old Trafford in their fifth group game of this season's Champions League. Jose Mourinho's side enters the midweek clash at the back of a 0-0 draw at home to Crystal Palace.
The Old Trafford outfit has struggled to perform at home this season winning just two out of eight appearances. Manchester United could face an overwhelming task should they fail to get a favorable result when it hosts a Young Boys side that fell to a 3-0 score at home in the first-leg.
However, Jose Mourinho does not believe that the upcoming match-up will be crucial to his side's chances of qualification.
"Tomorrow is not vital because even if we lose we depend on nobody but ourselves," he told reporters at Monday's media conference.
"But I want to play from minute one like it's the last chance we have to qualify. We have to win, that's the way I want to play.
"What I want is a team to start strong, not waiting. You probably thought Jose told them to start slow. It is exactly the opposite.
"I want them to start strong and go for it almost immediately."
Jose Mourinho went further to address Victor Lindelof's injury lay-off. The Swedish defender was pictured limping at the latter part of Sunday's Premier League draw with Crystal Palace.
"No chance he [Lindelof] will play tomorrow. He will be out for quite a while.
"We have [Eric] Bailly and [Phil] Jones, Marcos Rojo has some little injury and Victor a proper injury that will keep him out for a while, so Jones, Smalling and Bailly are the three we have.
"He [Lindelof] does the scan tomorrow but by the experience of the medical department and the feelings of the players, he has a muscular problem and muscular problem takes time.
"I would say if we have him for the Christmas period, where we need if possible every player to be available for that difficult period until the Newcastle match on 2 January, if we can have him available for that period it will be good."
Ahead if Tuesday's Champions League game, Manchester United momentarily sits in second place behind Juventus in Group H. The Red Devils trails Juventus by two points and also leads third-placed Valencia by the same number of points.
Los Che travels to take on Juventus at the Allianz Stadium on Tuesday.
