If we're going to play a flat back four and just two central midfielders, it's going to need a huge improvement from the four players through the middle on what we've been seeing lately from a three and a two - as the individuals concerned will, almost certainly include two from Morrison, Flint and Nelson at the back and two from Pack, Vaulks, Bacuna and, maybe, Ralls in the middle can we really expect that to happen?
