Nani had put the visitors ahead, but the Potters' £10m summer signing drew them level with a trademark header, and Pulis was delighted with his contribution.
"He's grabbed hold of what we're all about: the spirit and commitment and everybody together," said the Welshman.
"He'll be a very good signing for this football club and other players will learn off him as well. He's a great, great player."
Stoke's next game is a Europa League group match against Besiktas at home on Thursday.
