Foster says the minute he heard Pulis had got the job of replacing Alan Irvine, he knew their slide down the table was about to be halted.
He said: "He is tried and tested. You see what he's done at other football clubs and he's performed nothing short of miracles.
"He's a perfect fit. If we hadn't got him quickly someone else would have done. I reckon he could trademark the Tony Pulis formula for avoiding relegation.
"All he would have to do is get to around January and make himself available and he'd make a fortune!
"You see the results we've got and they are there for all to see. If you are needing to get out of a tight situation - he is your man.
"I said when he first joined that he is just gold dust for this club. He really is."
