We have other options of course. Go 4-4-2 with Vic and jelavic, start Hitzlsperger and move osman up, shift Pienaar into the middle to make room for oviedo, play Gueye to move Kev into the middle, hell if you want to despair we could go with neville and heitinga behind Osman.
But naismith has started a few games for us this season. I think he's the most obvious replacement for Fellaini.
That could happen and Ive totally forgot him in. the preview ffs.
