The thing that Im battling with in my mind about Fellaini is that I compare Fellaini's performances now to that of his last year (awful)... i.e he can only really improve. Im pleased for him thats he's playing better and against Man City was his best performance for me in a utd shirt.
However, if I was to compare him to other CM's in the league and i.e the teams and players we need to beat Im still not sure even with his current improved ability does he cut it when compared to: Matic, Ramieres, Fabregas, Yaya, Ramsey, Wilshere, Rooney (As a CM), Schneiderlin, even Henderson and Gerrard, Song. Im not so sure still.
Especially when I like the style of Herrera and currently Fellaini is being used in his place. Similarly Carrick next to Blind (once our defence is back) would be great to see, think against top sides they'd give us some real positional stability and platform to build from.
These are the calibre of player he needs to be IF he should be in a utd first team. I dont think us as fans should settle. Having said all of this should he and does he deserve to start against Arsenal yes, however if we are using his physicality as his main strength then when does he ever get dropped. Against shorter sides he becomes dominant against taller stronger sides he gives us a presence. Just struggling to get my head round it. Hopefully he just keeps improving and merits his place on a level to those other CM's in the league.
