You say that two sitters are important because of the full backs. I agree, if they are bombing up and down all game. But they haven't been they.'be been pushed right back and we now have a case of 6 defenders on the field.
The two sitters work, but it's very evident that there needs to be a plan b, there doesn't seem to be one. He always keeps those two anchors in midfield. You don't need two all the time.. When Barkley moved back in the derby he was fantastic in there and we looked great. We conceded from set pieces.
