Just to add to this Johnson has attempted 17 crosses in our opening 2 games and has been successful with 1 so far (6% success). Spence has attempted 6 and 1 has been successful (17%).
If we stick with wingbacks, those percentages need to be much higher.
You could see the shift in our targets early in the summer it was Murphy/Hoilett and a couple of wingers then around that time he went on TalkSport saying he tried to get Bolingoli on loan as a LB.
Then a few weeks later Marvin Johnsons given the number 3, Dijksteels a CB and Warnock omits all talk of wide signings. He's not wrong to assess our squad as suiting the 532 and given Dijksteels form as a wide CB why sacrifice him to RB in a back four whilst exposing Hall?
I think his problem now is to win games consistently with this system we need wingbacks that have consistency to their delivery because they get plenty of the ball in our attacks they're just ultra-wasteful.
