Riyad Mahrez climbed off the bench to fire Manchester City to a 1-0 win at Chelsea and cut the deficit to Premier League leaders Arsenal back to five points.
City, held to a draw by Everton on New Year’s Eve, were facing more frustration against an injury-hit yet enterprising Chelsea side at Stamford Bridge.
But less than three minutes after coming on as substitutes with an hour gone, Jack Grealish teed up Mahrez for the winner which keeps Arsenal firmly in their sights.
