By reaching the semi-finals, City will pay part of the sum negotiated for the winger. Further triggers will be activated if City win the tournament outright during Sterling’s ­period at the club.

Sterling is out with a groin injury but would hope to be in contention for a return should City make it to the final.

The 21-year-old moved to the ­Etihad last summer with the prospect of Champions League participation one reason he chose City.
