Second half goals from Gianluca Scamacca and Michail Antonio gave West Ham a 3-1 win over Fulham after opening goals from Andreas Pereira and Jarrod Bowen lef tit level at the break.
Pereira had opened the scoring early on after a powerful left-footed strike flew across Lukasz Fabianski in the West Ham goal to give the visitors a thrilling lead after just five minutes.
But the lead didn't last long, and it was Pereira who gave away the penalty that gave Bowen the opportunity to level for the hammers.
Italian forward Scamacca then gave the hosts the lead with a contemptuous flick over Bernd Leno to complete the comeback, before Antonio's stoppage time third ensured there was no comeback for the visitors.
