The Hammers' boss did reveal that he is sweating on the fitness of defender James Tomkins who has a hamstring complaint, but other than that, he has a full squad available ahead of two very difficult festive fixtures.
"James Tomkins is our only concern. He came off with a hamstring against Leicester and we'll know tomorrow if he's fit."
The side heads to Stamford Bridge in better shape than last season when they were in a relegation battle. This time they are fourth in the Premier League, facing Chelsea than Arsenal within the space of 24 hours, and Allardyce is hoping the side make a good account of themselves against the league leaders and at least get something from the game.
He said: "We're a completely different unit and we're enjoying our Christmas more this year. We do have the hardest games over 48 hours though.
"It was a part of our recovery. This time we've got better and younger players and hopefully we'll give a good account of ourselves.
"A good account of ourselves is a result, not a good performance and a loss."
These two games are a true test of the Hammers' credentials, and if they manage to somehow keep in the top four after these two fixtures they will be nicely positioned for the second half of the campaign.
