Jarrod Bowen's first half goal gave West Ham United all three points as we fell to our first home defeat in the Premier League this season.
Riccardo Calafiori had our best chance of the first half, firing straight at Alphonse Areola, before Bowen latched onto Aaron Wan-Bissaka's cross to give the visitors the lead.
Myles Lewis-Skelly was sent off for bringing down Mohammed Kudus in the second half as we looked to get a foothold in the game.
Leandro Trossard and Ben White came close but we failed to find an equaliser as we fell to a first defeat in the league since November 2.
