Barclays Premier League champions Chelsea travel to the Etihad Stadium on Sunday afternoon for a clash against fellow title rivals Manchester City.
With such a huge game coming so early in the season, take a look at four key battles that will shape the outcome of the match.
Raheem Sterling vs Branislav Ivanovic
The Blues right-back was given a torrid time against Swansea winger Jefferson Montero last weekend and he will have his hands full with Sterling on Sunday.
The former Liverpool winger was quiet on his debut against West Brom, but will surely be desperate to deliver on his first appearance in City colours at the Etihad.
