The club travel to the Luzhniki Stadium to play the second leg of their quarter-final tie against their Russian opponents after beating the same side 3-1 win at Stamford Bridge last week.
However, it also marks a return to the stadium where the club lost the 2008 Champions League final five years ago to Manchester United.

"You cannot just say, 'You and you and you'. The first thing, what matters, is that they have to be convinced they can score," Benitez told reporters.
"We are confident we will not need penalties. But if we do need penalties, we have enough experience and quality.
"I can remember the 2008 Champions League final, but I don't want to talk too much about that. It's not our problem now. Our problem now is Rubin Kazan.
"I don't want to lose the focus. It is another competition, in another time. Hopefully we can do well and everybody will not think too much about the past.
"Everybody will have bad memories but for us it is about the future."
Benitez also admitted that it will be challenging trying to combat complacency, a plastic pitch and the fact that the 80,000-capacity stadium is only likely to have as many as 10,000 fans all at once.
He added: "It will be a little strange. We will not get the extra motivation you normally get from a big, full, stadium. In this sort of situation the players can be too relaxed and go out there without the proper approach.
"So we have to send a message across to our players and then hopefully at the beginning of the game they will realise they need to be concentrated.
"But after what happened for Tottenham at Inter and us against Sparta Prague, they have been warned.
"We have to adapt to the pitch, although the new generation of synthetic pitches are better."
