West Ham United manager says that four members of his first-team squad are becoming frustrated.
Because of the form of the side, rotation hasn't been necessary and many of the players who have had to watch the success of the team from the sidelines are becoming frustrated.
"Even my trusted captain [Nolan] has found it difficult to break his way back into the side, so he's frustrated as are other players like Matt Jarvis, Ricardo Vaz Te and Joey O'Brien," Allardyce said to the club's official site.
"These were my regular players last season but because the players have done so well when they've not been available, it's difficult for me to put them back in based on the performances and results."
The Hammers summer recruitment drive has had such an impact that it seems that the disgruntled quartet could be waiting for their chances for some time yet.
West Ham have played with more style than they have shown in many seasons and possess some genuine quality in their squad.
The likes of Alex Song, Diafra Sakho and Enner Valencia have all been superb additions, but some rather more unsung buys such as Aaron Cresswell and Carl Jenkinson have also stepped-up well.
It leaves the London club in a better position than they have been in a number of years and they will be looking to continue to build on this success as the season progresses.
Already there is talk emerging of the potential for the side to break into the European spots and confidence is high around the Boleyn Ground.
The Hammers take on a Aston Villa this weekend and it seems that Allardyce may have to keep disappointing some of the underused members of his squad, as they look to inflict more pain on Paul Lambert's struggling side.
