funny thing is he should be mad at Ben Arfa, not Cissé. the formation change has been to suit him (you can't play him wide-right in a 4 if you want to get the best out of him) not Ba's Senegalese buddy. if Ben Arfa was still getting injured, Pardew would have stuck with 442 and it'd be Cissé and Ba up-front together making it rain.
but as Ben Arfa has stayed fit, the formation has shifted to 433 and even when he's up-front it's as a lone striker, so Ba is out of his element (whereas Cissé can thrive in that role, as his form has shown).
I feel bad for the guy.
