We obviously would. We have nothing like a central midfield to compete properly if we just play two in there. In 02/03 we had two from Rae/Ince/Cameron, in 08/09 we had Henry and Jones. We aren't anywhere near that level. Edwards works hard and knocks a few in, Price is neat and tidy but lacks range and mobility, Saiss is a better passer but is even slower, Saville is not a very good footballer, Evans is still trying to work out what on earth he is supposed to be, and Coady is wank in midfield. How are you picking a partnership out of that lot? They need to defend, attack and create as well as get up and down the pitch, no chance.
Costa wouldn't track back enough, nor would Cavaleiro and I'm not sure Weimann would either. Plus they all need to receive the ball way higher up the park than a 4-4-2 allows. It leaves no place for Bright. Doherty needs a DM AND a wide midfielder in front of him or he gets destroyed. Our centre halves are woeful with just one man in front of them, look at us through September-November for details.
Oh, and we don't have anything like a strike partnership worthy of persisting with, I must have seen Bod and Dicko nominally "together" now five times and on none of those occasions have they linked up at all, they don't know what their roles are and they offer less threat than when they're up there on their own. Leeds at home was painful to watch.
Otherwise yeah, let's go for it.
