Antonio Conte’s side went ahead in the 13th minute when Stoke goalkeeper Lee Grant could only palm Willian’s free-kick inside his own near post.
Mark Hughes’ men levelled through a Jonathan Walters penalty in the 38th minute, but they were denied a point when Cahill, who had conceded the spot-kick, made amends with a late winner which took the Blues 13 points clear at the top.

Arsene Wenger felt the venom of the Arsenal fans as his side’s Champions League hopes suffered another blow with a 3-1 loss at West Brom.
The Frenchman, who is yet to reveal whether he will remain in charge beyond the end of the season, saw his side beaten by two Craig Dawson headers, either side of a Hal Robson-Kanu goal.

Woeful defending contributed to Arsenal’s downfall.
Dawson headed home corners in the 12th and 75th minutes, while Robson-Kanu’s 55th-minute goal, just 75 seconds after coming on, came as a result of a collision between replacement goalkeeper David Ospina, on for the injured Petr Cech, and Hector Bellerin.

Leicester continued their remarkable resurgence under Craig Shakespeare as a flying start set them on their way to a 3-2 win at West Ham.

Andre Ayew headed home a second for the Hammers, but they could not find a leveller.
Victory maintained Shakespeare’s perfect record since replacing Claudio Ranieri and lifted his side six points clear of the bottom three.
