"I didn't know anything about it until an hour before the game, so I didn't have much time to think about it."
Goals from England pair Frank Lampard and John Terry condemned the Potters to a 2-0 defeat at Stamford Bridge.
"It was a weird game because normally we play with a bit higher tempo, but they had a lot of opportunities in the game and it was probably a fair result," continued the Germany international.
Pulis added that the target now for Stoke, currently 11th in the Premier League, is to reach 40 points and maintain their top-flight status for a third year.
"We have to put everything into context, and we have to make sure that we pick up some results in the league," he told BBC Radio Stoke.
"We've had a smashing season so far, but we mustn't take our foot off the pedal."
Stoke travel to Burnley on Wednesday, with midfielder Glenn Whelan doubtful after picking up a hamstring injury against the FA Cup holders.
