we're playing osman alongside gibson which is a bit more attacking than the gibson/fellaini partnership we had at the end of last season. so felli sitting deep and breaking up play alongside osman, won't be too much of a difference.
I'm just not convinced Fellaini can do Gibson's job without compromising what makes him so good. Hope he can prove me wrong but I think much like Mikel he works better with a mdifielder behind him and another midfielder in front.
