"I want the team to start strong, go strong on the opposition, not to be waiting", he said. It is exactly the opposite.
Although victory against Young Boys will guarantee United's passage to the knockout stage - providing Juventus avoid defeat by Valencia - Mourinho's side failed to score in recent home European games against Valencia and Juve, and Shaw conceded they are feeling the heat.
Meanwhile, Luke Shaw assured supporters the players are committed to helping the club recover from their poor start to the season after Mourinho accused the dressing room of lacking heart and desire after Saturday's draw. "Let's forget against Valencia, let's play this game like a game we have to win".
"If you feel pressure, stay at home - and when I say home, I don't say stadium home, I say home home and watch on TV", he said.
United will be without Victor Lindelof for several weeks after he suffered a suspected thigh injury against Palace, with Mourinho hopeful of having the Sweden centre-half back for the hectic Christmas period.
"That's not real pressure because the reality is we still have one match to play".
It was Fellaini and a quite sensational celebration from Mourinho that would steal that show in the end though as they somehow managed to win a game that appeared to be heading towards a goalless draw.
Per the Telegraph, a January move is possible, but only if Jose Mourinho is seen as the long term manager at the club.
Matteo Darmian, who started against Palace, was also missing from Monday's training, along with Marcos Rojo.
The combative Portuguese coach also confirmed that United should have no problem when it comes to getting to this home game. We are not coming from the city center. We train hard for the team and we're just looking forward to putting things right on Tuesday.
"I describe like is not a crucial match because if we don't win tomorrow we still don't depend on other results", he said, per the Mail.
"If you feel pressure to play matches at home where the people come to support... come on".
