CSKA's slim chance of reaching the next phase requires them to beat United as a first point of order, though Basel's result at Benfica and goal difference also have a part to play.
United had until 9pm (Singapore time) yesterday to decide whether to lodge an appeal.
A point will however be enough to see them through to the next round as they sit at the summit of the Group with 12 points, three ahead of the Swiss and the Russian sides.
Jose Mourinho believes there is a direct correlation between Victor Lindelof's improvement and Manchester United's form in recent weeks. He's working to have an opportunity and sooner or later, the opportunity will arrive, because he deserves that opportunity.
Mourinho confirmed he would be without Nemaja Matic, Zlatan Ibrahimovic, Marouane Fellaini, Michael Carrick, Phil Jones and Eric Bailly on Tuesday, while he will consider making changes before such a sizable league fixture.
Matic has helped to reinforce Mourinho's midfield and give Pogba more freedom to dictate Manchester United's momentum.
On Ibrahimovic, Mourinho said: "Zlatan is not injured".
"He [Ibrahimovic] is okay but he needs, now and again, specific work on the muscle that supports that knee that went through such a hard surgery", the boss told us.
"When a period of hard work comes, also the fatigue comes". He can not play for these days.
"He was on this cycle of work, divided between the gym and the pitch".
"It's just the next match [we are thinking about]".
"Easy, easy. We are used to it", he said of focusing on CSKA. We don't think about the next, just about tomorrow. "But I could make a surprise and one who isn't available may play".
