Manchester City’s advantage over Premier League leaders Arsenal has shrunk to five points as substitutes Riyad Mahrez and Jack Grealish combined to defeat Chelsea.

City struggled to break down Chelsea in the first half at Stamford Bridge, and Pep Guardiola had to make a host of substitutions to give his squad a spark.

This featured Grealish and Mahrez, with the England international scoring on 63 minutes with a superb cross to the back post.

Chelsea suffered injuries to Raheem Sterling and Christian Pulisic in the first half, adding to an already long list of absentees, leaving the Blues with only four points from their past five Premier League games under Graham Potter.
