That is something that they have achieved in six of their last eight competitive games and in their Europa League campaign last term, every single one of their games from the last 16 onwards finished with less than three goals.
It is an important game with both teams in need of a result for the same reasons.
Despite spending much of the game watching from afar, the Spaniard showcased razor-sharp instincts to block CSKA's shots on goal.
Golvin's presence was clearly sorely missed in the derby with the majority of CSKA's attack's subsequently very slow and unthreatening throughout the game.
Golovin managed to work another chance for the Russian's, and the CSKA fans were in full voice, but it couldn't prevent United going three up just before the half hour mark. But sadly, Mario Fernandes sustained a concussion during the match and won't available for Wednesday's game against ManU. I'm also mildly concerned that they played Dinamo Moscow on Saturday and could only draw 0-0 - although it was away from home. However, Mourinho's side will travel without key midfielder Marouane Fellaini after the Belgian was ruled out through injury.
The second half was a different story, however, and the Saints got more involved in the game, applying pressure and creating good openings. "The solutions are not many", Mourinho said.
CSKA coach Viktor Goncharenko said Ander Herrera could take on Fellaini's role in midfield alongside Nemanja Matic, but added he didn't expect the switch to leave any weak points.
I do not speak about opposition players because if I speak well about them, I motivate them.
CSKA couldn't have dreamt of a worse start to proceedings with Lukaku - scoring for the seventh game in succession - putting United 1-0 up after just four minutes.More news: Meghan Markle Kept Away From Prince Harry At Invictus Opening Ceremony

Phil Jones is unavailable, which is likely to thrust Victor Lindelof into the lineup again. Marouane Fellaini, moreover, suffered an ankle injury in the weekend's victory. "That's enough for me".
"Everyone knows that football is not only 90 minutes", he said.
"But we try not to focus on individual battles on the pitch, we are going to have a team with quality and balance to try to win the match, which is the objective". Having defeated Rostov 2-0, CSKA then flew out of the Cup of Russian Federation from the modest Vanguard - 0-1, and in the last match played a zero draw with Moscow's Dynamo.

With a quarter of the match gone, United looked very comfortable, knocking the ball around easily and orchestrating chances, one of which they should have buried, with Mkhitaryan hitting Daley Blind's low ball straight at the feet of goalkeeper Akineev from eight yards.
Belgium global Fellaini was added to the absentee list after a Shane Long tackle in Saturday's win over Southampton injured his ankle and, with Carrick also missing, Ander Herrera is set to start.
The former England global has a wealth of European experience and he could prove a vital asset on the ball, helping to forge opportunities from his deep position.
Mourinho's men are top of Group A having beaten Basel 3-0 at Old Trafford and it really wouldn't surprise me if the manager would view a point at CSKA as a decent return.
