Ave Stoke changed anything ?

They seem to play the same cynical way under Hughes as they did with Pulis. Crouch using Rio as a climbing frame, i thought the use of the arm was illegal. So, how was Stokes first goal allowed to stand ? Why is Shawcoss allowed to get away with blatent obstruction at nearly every corner and set piece ? Watching im yesterday was a terrible advert for the English Premier. Stoke can change managers but they can't change the way they play.
