"They have been one of the main reasons why we have stayed up - they have made this place a fortress," Pulis said of the fans.

"I think they have set the standard and that has really set us apart from the others."
Pulis confirmed the 2009/2010 season is going to be a delicate balance about keeping the essence of what has made Stoke successful this campaign and finding new additions to improve the side.
The Potters boss added: "I think we have got to keep the same DNA and it's just (adding) better quality I'll work out how to do that.
"The group of players, the 11 who started today were fantastic and group that's behind them have been fantastic as well."
