Let's take a look at the current CL table:

This is how playoff and direct qualifiers places look like. Yeah, there is no Manchester City there. Crazy, right?

They have the same points as Stuttgart and follow them right behind. It would be a huge disappointment if they fail to throw themselves in playoffs. The last one is vs Club Brugge home. I guess Guardiola wouldn't make the fans sad by losing points in such game. The biggest issue of them has been to play terrible against top clubs. So we can still see them getting eliminated by such club in the phase right after this one.
