Pulis reckons their firs-half showing was down to nerves.
Ricardo Fuller scored the only goal of the game in the 74th minute, while Stoke keeper Thomas Sorensen saved a penalty from Kevin Prince Boateng.
“I thought first-half that was as poor as we have played especially at home,” Pulis told Sky Sports.
“Thomas kept us in the game with the save. We never really caused them problems but if you look at the game I think they only had two shots on target as well and one was the penalty and although they played some good stuff they never got in behind us and caused us too much problems.
“(I think we were) nervous as much as anything else although it was difficult conditions.
“We played really, really well against Wolves (last home game) in the first-half going in 2-0 up and then second-half we conceded two goals and then we went to Hull and got beat, so that was a blow for us, and they were a little bit on the back foot, but second half we were better.”
