Alexis Mac Allister successfully converted from 12 yards before Leandro Trossard's 66th minute goal to maintain Brighton's unbeaten start to the 2022-23 season with a 2-0 win over West Ham, who are still yet to score a goal or win a single point.
Mac Allister stepped up in the 22nd minute to confidently convert the penalty won by Danny Welbeck after he was taken down by new Hammers signing Thilo Kehrer, who was shown a yellow on a debut he will want to quickly put behind him.
Trossard then doubled the visitors' lead after the hour mark, latching onto Pascal Gross' flick on from a Mac Allister pass before slotting coolly past Fabianski to secure the points for the Seagulls.
