The Potters dropped to 16th following Sunday's 2-0 home defeat to Manchester United and will now undertake a new season within a season in a bid to stave off relegation.
"I've just spoken to the players. It's a five-game season," Pulis told Sky Sports.
"There's eight, maybe nine teams that are in the scrap and we've just got to make sure, no matter what's happened before, the season really starts for us now. I still say 40 points will do it."
