West Ham manager Sam Allardyce has said he is determined to revel in West Ham's best start to a season in almost 30 years.
Andy Carroll and Stewart Downing were on target in a 2-0 win over Leicester which means the Hammers are fourth in the Premier League at Christmas.
It is their highest position on Dec. 25 since the 1985-86 season, when they finished third.
With Chelsea and Arsenal the next opposition Allardyce was concentrating on "enjoying the moment" and said: "It's not often a team are breaking the barriers everybody else doesn't expect them to break.
"You should enjoy the moment and continue to enjoy the moment for as long as it lasts. Hopefully it will last for a good while yet.
"We've sustained our position between sixth and fourth in recent weeks. We've a considerable amount of games now. The end of January will tell us what we can possibly achieve.
"It's about the consistency of winning, and that is what we've got to challenge ourselves to try to do. You can't afford to slip up too many times if you've played well and you don't win, because you'll end up slipping away and out of the elite end of this league.
"At the moment we're living with it, we're enjoying it and the players who have applied themselves magnificently well all season are reaping the rewards."
Leicester, whose winless run was extended to 12 games, were culpable as West Ham claimed a fourth win in five games.
Paul Konchesky, playing against his old club, presented Carroll with the opening goal moments after the Hammers striker had missed a straightforward opportunity.
But there was little Leicester could do to stop Downing's strike, as the playmaker curled a sumptuous shot into the far corner.
Adrian saved well to deny substitutes David Nugent and Leonardo Ulloa late on as West Ham kept a clean sheet in a comfortable win.
"We've had a very good day," Allardyce added. "Everybody expected us to win. We have won. That gives us a little bit of leeway."
"The whole team is playing really well, but Stewart crowned off a very good performance again with another goal. His outstanding contributions on a consistent basis have been a revelation for us this season."
