Manchester City boss Pep Guardiola sees their clash with Olympiakos as an opportunity to put one foot in the knockout phase of the Champions League.
City have back-to-back wins so far in Europe.
Guardiola said, "You know in Europe you have to secure home games and win at least one away.
"We did it, winning in Marseille. But we know we have to secure points at home.
"We won the first two games. Porto was difficult and Marseille we handled so well and was in control. Now we have Olympiakos and we can leave them behind us and this is the target.
"Some players can handle three, four, five games with no problems. Others struggle more. Now we're beginning November. We know how demanding this country is.
"That's why tomorrow is important to get to nine points, get close to qualification and handle PL better."
