GOALS from Alexis Mac Allister and Leandro Trossard condemned West Ham to a 2-0 defeat today at home to bogey side Brighton in English football’s Premier League.

Mac Allister’s first-half penalty and Trossard’s breakaway goal maintained Brighton’s unbeaten start to the season and made it three defeats from three matches for the Hammers.

West Ham have now played the Seagulls 11 times in the Premier League and not beaten them once.

Defender Thilo Kehrer was given a full debut, but his Premier League career started inauspiciously when he brought down Danny Welbeck to concede a penalty.

Kurt Zouma had given the ball away in the middle of the pitch and Trossard’s pass found Welbeck, who was tripped on the edge of the area by the signing from Paris St Germain. After VAR confirmed the foul was inside the box, Mac Allister stepped up to fire the Seagulls into a 22nd-minute lead.

Kehrer was enduring a torrid debut and, after another defensive mix-up, found himself wiped out by his own goalkeeper, Lukasz Fabianksi, before the ball was cleared.

With Brighton looking comfortable, Trossard had a shot blocked at the far post and Joel Veltman missed a simple header from six yards.

It was an abject first-half display from West Ham, with Said Benrahma’s early curler, which sailed wide, their only genuine attempt on goal, and they were booed off at the interval.

Presumably manager David Moyes did not mince his words at half time as West Ham began the second half with far more purpose.

Declan Rice had a shot deflected wide, Aaron Cresswell’s volley was blocked and Brighton keeper Robert Sanchez held a drive from Pablo Fornals.

The Hammers’ Italy striker Gianluca Scamacca made his entrance on the hour mark but five minutes later they were hit with a sucker punch as Brighton doubled their lead.

Mac Allister’s pass forward found Pascal Gross, who beautifully held off Zouma while flicking the ball into the path of Trossard for a neat finish past Fabianski.

The visitors could have a had a deserved third but Solly March headed an inviting cross from substitute Pervis Estupinan narrowly over.

West Ham were denied a consolation goal late on, when Sanchez palmed headers from Jarrod Bowen and then Tomas Soucek over the crossbar.
