The only way this game won't be the decider is if we are already through. We will beat Moscow at home, and possibly Bayern as well considering they will likely already be through. Roma have to go to Moscow and it will be freezing - they should win but you never know. Whilst it is likely the Roma v City game will have Bayern on 15pts, Roma on 7pts and City on 5pts meaning we have to win... it could well be different. It is unlikely though that the group will be decided before that game. I'm weirdly confident we will get through. We've done well in the CL away games under Pellegrini in general - won the 3 last season and played well in Barca. We were unlucky away at Bayern this time and should have held on in Moscow. I'd be more confident in us winning in Rome than having Roma at our place - which is odd considering how good we are at home generally in the league.
