Bayer Leverkusen scored twice in the last 10 minutes to break West Ham's resistance and take the advantage after the first leg of their Europa League quarter-final.
Jonas Hofmann fired through a crowd of bodies for Xabi Alonso's side after the visitors struggled to clear a corner with seven minutes remaining.
Victor Boniface then doubled the lead in the first minute of injury time with a well-directed header from Hofmann's cross.
Alonso's hosts dominated possession but were largely frustrated by a superbly organised Hammers defence until Hofmann's late intervention.
The visitors showed great discipline to limit Leverkusen's chances for much of the game while also offering a threat on the counter through the pace and power of Michail Antonio.
Antonio created arguably the best opportunity of the match as he broke down the left and squared for Mohammed Kudus, but the Ghana winger's shot was straight at Leverkusen goalkeeper Matej Kovar.
West Ham did need a couple of very smart saves from Lukasz Fabianski as the 38-year-old keeper got down to deny Patrick Schick in the first half before leaping to tip the striker's header over the bar in the second when he looked to have been wrong-footed.
Hoffman finally found a way past Fabianski and when Boniface nodded in the second, Leverkusen were assured of victory to stretch their unbeaten run to 42 matches.

This is not the overrated English league this is European competitions wether you are at Anfield or not it only matters in England. Out of the overrated English league it's another game and I like the way Atalanta vandalised the Anfield forest. While West ham looked like a 3rd division Bundles Liga team against Leverkusen 😂 😂

Since Liverpool and Milan have a slim chance to go through to the semifinal, looks like Leverkusen will be the one who lift the Europa League this season..
