United will take on Feyenoord at a half-full De Kuip stadium as the Dutch side have voluntarily reduced their stadium capacity to avoid the crowd trouble that erupted in their round of 32 fixture last year against Roma.
Only 1,400 United supporters will be allowed to attend the game as a result of the reductions.
“There is not player or manager who wants to play in an empty stadium,” added Mourinho.
“We are lucky it is not closed, just half of it, but half is not the same as full. Every player wants a great atmosphere.
“I remember clearly what happened against Roma. I don’t think this is Feyenoord, Feyenoord is much bigger than a few hundred that created that situation. But in the end the clubs are punished by this actions.
“The players are going to be punished, I am punished, van Bronckhorst will be punished.
“I have played here in friendly matches and I know the atmosphere will be good with half of it.”
