Having gone toe to toe in a dramatic title rice that went right to the wire the season before, the sides locked horns again in the annual curtain raiser at Wembley Stadium, where Raheem Sterling bundled in to give City an early lead.
Joel Matip headed home from close range to level the scores with 13 minutes remaining and, after a goalless extra-time, the game was settled via a penalty shootout, in which Claudio Bravo was the hero.
The Chilean denied Georginio Wijnaldum – the only player to miss – which allowed Gabriel Jesus to stroke home the winner as City converted all five spot-kicks.
