Richard, who came on as a second half substitute against Manchester United on Sunday, says the Hammers can get back to winning ways at the 15th time of asking in the Premiership.
"I think after the game the morale was pretty low but in the days to come we will lift ourselves up for Wednesday," insists Richard, whose return came after a shin injury left him sidelined for nearly two months.
"We are just looking forward to that and the boys are pretty pumped to rectify Sunday's game.
"Sometimes you need these things as a wake up call to say 'hey, it's time to start playing better' and hopefully we can start now.
"We have to concentrate on our games, get back to basics - and get back to winning games.
"I don't think we will go down; we have got the quality, the boys will turn it around and if we get a good result on Wednesday it is onward from there."
Richard came on with Christian Dailly and Glen Johnson - and at least helped prevent the scoreline getting any worse.
"I think the game was pretty much gone at 6-0 with 10 minutes to go so the boys weren't best pleased, but that's football - we have to bounce back from this and there are 14 games to go in which we hope to play better," he says.
"How can you not be disappointed? We played well in patches but it just wasn't there.
"I was glad to get on in the sense of getting a run but it was not the best of circumstances, and now I will be hoping to push on and get some more minutes on the park - perhaps a half hour spell.
"We will have to see how the season progresses, but I feel that I have got something to offer the team and I want to do my bit to try and help the boys stay up.
"They kept the ball well and their movement was fantastic while we had a few injuries - and made mistakes that cost us goals, which was our downfall."
