Macari said on MUTV: "There are a lot of players you like to think that they can step-up but can they?"
"If you feel pressure where people come to support, stay and watch on TV. I never felt pressure to play at home".
"I refuse to say that because I don't want to disrespect the home fans", he fired.
"Do I prefer to play Young Boys here or go to Bern?" "I want my players to be strong".
With United able to qualify for the knockout rounds tomorrow if they beat Young Boys and Juventus don't lose to Valencia, Mourinho wants his players to go all-out for victory and treat the game as a knockout match.
The opening two Champions League Group H encounters at home to Valencia and Juventus ended with a draw and a defeat respectively as United failed to score on both occasions. Mourinho was forced to walk the last half mile and the 55-year-old insists he is prepared to do the same again.
Manchester United have always been linked with a move for West Ham United's Marko Arnautovic and reports are suggesting that they are ready to offer more than £50m for his services. Information is that things will be much better than last time.

DUP putting 'precious union' ahead of everything in Brexit deal - Varadkar
The party has repeatedly said it will not back the deal because of the backstop, which aims to avoid a hard Irish border. Also due to appear at the conference on Saturday afternoon is the chief minister of Gibraltar, Fabian Picardo.
Matteo Darmian, who started against Palace, was also missing, along with Marcos Rojo.
Mourinho's woes were further compounded when he confirmed that his much improved and increasingly influential Sweden defender Victor Lindelöf will be absent because of a muscle injury - nearly certainly his thigh - and could also be sidelined over the impending festive period.
"It was a really good performance and at least we got something from the game", Palace manager Roy Hodgson said.
"I think we need to keep working hard as a team and creating those chances and ultimately finishing them and making sure the games that we are dominate we win".
"There are games that are special and not just one more: this was a special game, the first of eight Premier League games until the end of December and it was a game we need to win and my feeling is that it was not enough from the heart".
Mourinho was reluctant to accept that United are better away from home at the moment, but he had an emphatic message for any player who felt cowed by the prospect of playing at Old Trafford.
"Sometimes, of course, it might look like that [players don't have enough desire] but I look in the training ground and I look around the changing room and I think everyone wants the same and that's to win games and to climb up the table", said Shaw.
