Manchester City boss Manuel Pellegrini says the home game against Bayern Munich on November 25 could be the key to his side's hopes of advancing past the group stage in the Champions League.
The Citizens could only manage a draw against in-form Roma with the Chilean clearly unhappy for a disappointing draw at home leaving his side already five points from leaders Bayern Munich.
"We don't know [how difficult it is to qualify]. It depends on the way we play the next game," Pellegrini said during his post-match press conference.
"We have just one point from six but also we are just three points behind Roma, so there is a lot of things [to play for].
"We hope next game in Russia we can win and we will see what happens against Bayern Munich.
"We have 12 more points to fight [for] and we will fight to the end to try and qualify.
"Roma are a team in form with great players. They made it difficult for us, it was a difficult game but I thought we could win it in the last 20 minutes.
"A point playing at home is never good but we played against a very strong team in a very good moment [of form].
"We didn't play well, especially in the first half. We improved in the second half but I think the draw was the real [right] thing for both teams.
"We must continue fighting for the next 12 points and we will see which teams qualify for the next round.
Goalkeeper Joe Hart looked too eager to leave his line when Francesco Totti restored parity for the visitors but Pellegrini opted not to focus on individual mistakes.
"I think that when the other team scores a goal it is not just a problem of one or two players. I think that he had too much space in that play.
"Maybe it was an easy goal for them but you must have the quality and the capacity to return to your normal performance. Today was not our day.
