Mohammed Kudus has just scored a goal of the season contender to pull one back for West Ham right at the brink of half-time.
Manchester City were cruising into the title with two early goals courtesy of Phil Foden.
But Kudus has changed the mood around Etihad with a stunning goal in the 42nd minute.
The goal comes from an inswinging corner from James Ward-Prowse. Gvardiol fails to deal with it as a West Ham player gets his head on to the ball which falls in the path of Kudus.
