Manchester United opened up their Champions League group stage play with an emphatic 3-0 win.
Having achieved an important victory on the field of "Benfica" - 2: 1, CSKA probably made the biggest step forward in this Champions League.
It's also worth noting that according to Opta, Manchester United's five away games against Russian clubs in all competitions have produced only five goals (3 for, 2 against).
But the impressive Fellaini is a blow for the Portuguese, after the big Belgian showed he can be a big part of Mourinho's plans with a strong start to the season for United.
A win on Wednesday would see Man Utd go three points clear at the top of Champions League Group A, with CSKA now behind the Old Trafford side on goal difference alone.

The Belgian striker had his header denied but quick thinking saw him finally score the only goal in the 1-0 win. He added to MUTV: "Three fantastic points - the same points as when we win 4-0".
For this United side, they'll once again be without star Paul Pogba.
"There are three midfielders that we lose for this match, so the solutions are not many".
"We try not to focus on individual battles or specific areas on the pitch".
It would be interesting to see, however, if CSKA Moscow could overcome a strong Manchester United firing on all cylinders. He's now met CSKA seven times with four different clubs - and has won six and drawn the other.
According to reports in Russia, CSKA Moscow's main concern surrounds Mario Fernandes after being taken off with a concussion on Saturday.
I think Natkho will keep his place from the weekend to add more defensive cover for Goncharenko side in light of United's counter-attacking threat.
Both were also left out of the win over Basle at Old Trafford a fortnight ago but have started every Premier League game so far.
"We try to play well and in some moments of the match, if the opponent has moments of superiority, we have to be humble - like we were against Southampton - and cope with the hard moments of the game".
