West Ham midfielder James Ward-Prowse admits the players must respond to Sunday’s home meltdown.
The Hammers were thrashed 0-6 by Arsenal.
Ward-Prowse told the club’s website: “There’s now a good chance to show a reaction and show something rather than just saying a few words.
“We can all accept losing a game, that happens in football, but I think the way you lose is important and the most disappointing thing is the way we lost the game.
“I don’t feel like we competed anywhere near the level you need to in the Premier League.
“Of course, they’re a top team who are challenging for the title, but I think they showed us today the level and the detail that you need to win games.”
West Ham return to action this weekend against Nottingham Forest.
