We suffered our first Premier League defeat since November as Jarred Bowen's first-half goal was enough to give West Ham all three points, and you can watch all the key moments now.
The Hammers' captain nodded home from close range following a swift counter-attack before Myles Lewis-Skelly was shown a red card in the second half after bringing down Mohammed Kudus as we attempted to get back into the contest.
Leandro Trossard and Ben White went close but we couldn't make the breakthrough as the visitors secured back-to-back away wins at Emirates Stadium.
