Nothing fickle about not wanting to put up with s***.
I'd say it was fickle to do it first game of the season with new players getting used to each other and still getting their fitness and sharpness against the Champions who've bought big again... I'd find it totally acceptable after half a dozen games if nothing has improved with regards to the playing style and results...
I wouldn't give Pardew has been proven to be nothing but a big giant smug faced turd who has never succeeded in his complete joke of a career.
Let's be clear here, boos would be directed at Pardew for being a fraud.
