Graham Potter bought himself some time in the Chelsea dugout as Wesley Fofana's second-half header delivered a vital 1-0 win over old rivals Leeds at Stamford Bridge on Saturday.

The hosts dominated from the first whistle and had three glorious chances to take the lead through Wesley Fofana, Kai Havertz and Joao Felix, with the latter thumping the crossbar.

The Blues were forced to wait until early in the second period to get the all important winner, though, as Fofana rose highest to nod a corner into the back of the net. Despite Chelsea missing a litany of goalscoring chances, that proved to be enough for a crucial three points.
