Ben Arfa, like Ba at the time, needs games.
Simply put.
With games comes progress, I'm sure after a run of them, Ben Arfa will be fine.
From the article Dave posted above:
The player himself feels good so I think it's a matter of time before Ben Arfa will be a regular in the side. I mentioned this before, when Ba goes to the ACoN, that's Ben Arfa's chance to try and shine.
i could understand not playing him in every game over a supposedly busy period but he's proved he can handle 90mins so why drop him to the bench for weeks on end.
Ben Arfa should start against Liverpool and subsequent games after that, no doubt about that in my mind.
It's just that going by Pardew's comments, it just seems to me that Ben Arfa isn't going to get a proper chance until Ba heads off to the ACoN.
