The interview's greatest significance resides in the unusual candour Mourinho shows about the gulf between the capabilities and expectations of the United side he has inherited, which included a declaration that he never sees the club returning to the kind of domination Old Trafford knew under Alex Ferguson.
"We are in the Premier League - obviously not playing for the championship - but playing for the third or fourth position, and trying to win the Europa League".
United manager Jose Mourinho confirmed Pogba will be sidelined after having to be replaced two minutes into the second half of Thursday's Europa League victory over the Russians.
Mourinho says it is time English football took a leaf out of the book of other countries who assist their teams in Europe with the fixtures. But here it is hard. "But a lot of things are going against us", he told BT Sport at Old Trafford. We go with what we have.
United played in the FA Cup on Monday, losing to Chelsea. It's hard to play 12 o'clock on Sunday.
I've said this for many years. "We played against one of the best teams in the world. Whoever decided the Monday and Sunday games probably thinks the same way". "Not 12 o'clock. At least let us sleep a little bit on Sunday, right?"
Mourinho indirectly blamed his side's jam-packed fixture schedule and said Pogba's injury was due to "fatigue".
Mourinho, who worked under Van Gaal at Barcelona, has becoming increasing critical of his one-time mentor during his first season as the Dutchman's successor and said in an interview with the BBC's Gary Lineker that the club has fallen so far that fans have an unreal expectation that the club is "ready to win everything".
Argentine playmaker Di Maria, who started brightly following his arrival from Real Madrid in 2014 but struggled for form and fitness in the latter part of the season, was sold after one year, while England forward Welbeck was allowed to leave for Arsenal during Van Gaal's first transfer window.
"I think the same with our supporters in the stadium and never felt anything but feel safe and feel super comfortable". More famously, they were the team on the receiving end of the Reds' record scoreline - 10-0 - a fortnight later, in a game played under the floodlights at Manchester City's Maine Road ground.
