Hammers boss Sam Allardyce has his eyes set on an unlikely double when his team travel to Chelsea in the Barclays Premier League on Sunday.
West Ham last achieved two league wins over Chelsea in the same season back in 2002/03, but following December's 3-1 triumph at the Boleyn Ground, they have the opportunity to put that record right this weekend.
Allardyce, however, is well aware of the size of the task facing his team.
He told whufc.com: "It would be our first double of the year, we've had many other opportunities that we've blown. It would be an absolutely unbelievable result for us to win at Stamford Bridge and do the double over Chelsea in the same season. It's one of those things that happens rarely, for you to be able to beat a top side home and away. It's a great incentive for the lads to go out there and achieve that on Sunday.
"On the basis that they played on Thursday night, we certainly should have the energy levels to cope with, as best we can, the quality that Chelsea have. The high intensity levels that we'll need to achieve to nullify a Chelsea side are pretty big, especially out of possession.
"We should have enough to try and stay in the game as long as possible. We obviously want to score first if we can, but if we can't, as long as we keep the game tight, then inevitably they must tire based on the workload they have had and you can find some gaps and spaces."
Allardyce is not expecting injured trio Mark Noble, Kevin Nolan and Joe Cole to return, although he revealed that Matt Taylor has recovered well from the blow he received to his jaw at Stoke two weeks ago.
He continued: "Of those with knocks, there's only Taylor who has recovered and in training at the moment. The other three - Mark Noble, Kevin Nolan and Joe Cole - are still pretty doubtful for selection on Sunday, even though we've had two weeks since our last game, it's looks as if they've not been able to recover in time.
"We've been managing situations like this [gaps between matches] for a long time now, with international breaks. All we can do is what we did last time we played - win. Because it makes that two weeks pretty pleasurable, in terms of handling and getting through the fortnight.
"So our win at Stoke was a massive bonus for us. We've got exactly the same situation on Sunday, where we've got two weeks before we play West Brom. We've just got to manage it the best way we can.
"We're in a very good position, but mathematically we need to get a little closer and we need another five points. I think 38 points will be safe this year, but we'll all aim for 40, just in case."
