I don’t think that’s what Ole wants to implement. Use the westham game as an example, our team play has change a lot. Our CB and fullbacks played high line a lot more in a very solid way during possession. During the defensive phase, the back line and midfield shift and move more significantly. It’s kinda like how pool normally does. McFred, Bruno, Pogba, and our back line did very well together. It’s still a work in process apparently, but the westham game in my opinion, is one of our best performances against a low-block opponent.Ole is persisting with it because it's getting him results more often than not. The truth is it does offer us more solidity whether we choose to see it or not. Ole clearly just wants the 2 in front to protect the defence and let the 4 in front do all the attacking with assistance from the full backs.
For now McFred are our only viable options who can do that job.
