Manchester City reached the Champions League's round of 16 despite an unconvincing 1-1 draw at home to Ukraine's Shakhtar Donetsk at the Etihad Stadium on Tuesday.
Ilkay Gundogan had fired City ahead in the 56th minute but Shakhtar earned a potentially valuable point after Israeli substitute Manor Soloman equalised in the 69th.
Atalanta's 2-0 victory over Dinamo Zagreb in Group C's other game meant that Pep Guardiola's side are guaranteed to finish top.
City have 11 points at the summit ahead of their final group game away to Dinamo with Shakhtar in second place on six points. Dinamo have five points and Atalanta four.
Yet while the goal of qualification was secured, it was a far from impressive performance from a team which harbours ambitions of a first Champions League triumph this season.
For Shakhtar everything is still to play for in their final match, at home to Atalanta on Dec. 11, with all three teams in the group still having a chance to join City in the knockout stage.
At a subdued Etihad, City survived a scare in the 15th minute when their Brazilian goalkeeper Ederson raced out of his area and completely missed the ball as he attempted to clear.
That allowed Mateus Tete to break towards the unguarded goal, but Fernandinho did superbly to cover the near post and block his compatriot's shot.
Moments later, Ederson raced outside his box again but this time his intervention was well-timed and clean, as he slid to clear the danger with Tete threatening once more.
After a mostly uneventful remainder of the first half, City got themselves in front when Gabriel Jesus twisted and turned in the box before poking the ball to Gundogan who slotted home.
Yet Shakhtar drew level with a perfectly-constructed break that ended with Israeli substitute Manor Solomon drilling past Ederson after an excellent pull-back from Dodo.
