The striker headed in an 85th-minute winner to condemn the Hammers to a seventh defeat in nine games, while Fulham has now won three league matches in a row to move into the top half of the Premier League.

Alphonse Areola tipped Harry Wilson's fizzing long-range drive over the bar, while the West Ham goalkeeper just about kept out Joachim Andersen's swerving attempt from distance with his feet.

The Hammers improved after the break, but saw a golden opportunity go begging in the 65th minute, with Jarrod Bowen unable to steer home Soungoutou Magassa's cutback from inside the six-yard box.

Substitute Callum Wilson was also marginally off target with two attempts, before Fulham snatched all three points with five minutes remaining.

After Ollie Scarles failed to clear Harry Wilson's initial cross, the Wales international's follow-up delivery was nodded in by Jimenez before the Cottagers held off any late attempts of a comeback.
