The 6/8/10 midfield positions don't seem to mean much this year. The midfield shows up in a tight cluster on the heat maps, and I'm constantly surprised to see Maxi play deep so often, receiving short passes from the defense.
More important that they understand each other and work together. I would be more than fine with an physical 8 that can go forward, as long as they understand when to control those runs with their teammates.
Question on this for people who understand this stuff better than me. Does the cluster have to do with the fact that we sometimes press? Ring and Pirlo (not as much) sometimes act as a nuisance to the opposition's back line. Does that distort the heat map?
