Sunderland face the prospect of playing three games within the space of eight days to close their season.
The Black Cats kick off their final trio of matches with a game against Chelsea, before they take on Everton in midweek.
Sunderland then finish their season with a fixture against Watford at Vicarage Road, and Allardyce has hinted that he intends to ensure that his side avoid fatigue.
“We’ll probably change the side more in these three games than we have done since the turn of the year,” he said.
“Since the players have all been fit, then some have been frustrated.
“I changed the team every week when I first got here, and nobody knew who we were playing, where they were playing and when they were playing on the basis that we were rubbish.
“But since the turn of the year and we’ve got better and better, the form of the players has hit a level where I’ve found it very difficult to drop them.”
Allardyce has generally picked a stable starting line-up over recent weeks, and their performances have been encouraging.
Sunderland have proven difficult to beat of late, but they have not won on a regular enough basis to move away from trouble.
As things stand, Sunderland are in 18th place in the Premier League table - one point adrift of safety.
Sunderland drew their last match against Stoke City 1-1, thanks to a last minute equaliser from Jermain Defoe.
