Carlton Cole admits West Ham United boss Sam Allardyce has warned the players not to be complacent.
West Ham go to Stoke City this weekend fresh from victory over Manchester City.
Cole told whufc.com: "The boys are buzzing, we maintained fourth position last weekend so everyone is in a good mood around the training ground and everyone wants to progress.
"The manager said in our meeting on Tuesday that we can't be complacent. We have to keep going, keep firing on all cylinders and take advantage of the situation we're in.
"Of course last Saturday is up there with my top results at West Ham. I remember beating Manchester City 1-0 in 2009 when Jack Collison scored, but that was the last time we beat them before Saturday.
"It was a big scalp for us and it just shows the progression we've made. We just want to keep on producing and churning out the results."
