Manchester City are hoping to go one better than their domestic treble of last season and finally land the trophy that has eluded them.
The Etihad club are still yet to win a European Cup in their illustrious history, despite going close on more than one occasion.
Manager Pep Guardiola hasn't got his hands on the Champions League since his time at Barcelona , and is thought to be prioritising the competition this season.
City were desperately unlucky to be eliminated in the last campaign as VAR ruled out Raheem Sterling's late strike due to an offside in the build-up.
They've been entered in pot one after winning the Premier League so have avoided some of their fellow big guns.
Here is who City will face in the group stages...

Shakhtar Donetsk
