I can see that shape in it at times, generally was just trying to emphasise Neves being the standout as the deepest midfielder rather than his standing in relation to the back three, though at times it even ends up almost like a four with him dropping between centre halves to get on the ball. Either way, it's too many bodies wasted behind the ball when teams are just sticking everyone goal side, unless you're drawing people out to press then it's never going to hurt them having so much of the ball and so many passing options in those areas.
You want Coady to become a ghost?
I think the idea that improving on Bennett's perceived shortcomings producing massive improvements it's often well overblown, Boly looks a lot more comfortable on the ball but generally his passing isn't that much more adventurous than the man on the other side. It's not like either of them are going to be threading the ball through into players in threatening positions with any great regularity, as long as they're tidy on the ball and keep the tempo up recycling possession they're doing enough, what will really make a difference is more passing options ahead of the ball and in between the opposition lines.
