Ben Arfa'd playing has never really been the big problem. The talent has always been undeniable. Problem was always his fights/arguments with coaches/teammates/management....and than some horrific injuries like the leg break caused by De Jong.
I don't think we should be doubting his ability. In terms of ability he'd easily be the best winger in the club. If he stays healthy (which apart from a couple of minor things, he's done this year) and doesn't get "pissy" (again, he hasn't done this in a while too, or I haven't read anything)...than he'd be a quality signing. The fact that he'd come on a free, is a big bonus.
