It is usual to have a combo in CM of a tall and a smallish player: Busquets and Xavi, Casemiro and Modric, Matic and Kante (now Bakayoko and Kante), Fernandinho and Toure, Carrick and Scholes and so on. Most of these tall players are in between 185 and 190 cm. It is very rare to have two players over 190 in CM. I reckon there is no elite professional team with two such players.
Now, Jose and most people on here think that this isn't a problem at all because Pogba and Matic happen to be very good on the ball and are not slow. Thus, Jose sort of combines the best features of two worlds - that of the technical but physically unimpressive players and that of the physical beasts who are a bit clumsy on the ball. My qualm is that combining two very tall players - 191 and 194 cm - in CM may have not only the obvious benefits but also some costs - mostly with regard to dynamism, tempo, quick reactions in midfield, slow and disrupted build-up when intensly pressed by the opposition. I think we kind of witnessed these problems vs Madrid when for a large part of the game United looked poor. Because that was Madrid who have a fantastic team (even without Ronaldo) and because the final result (a minimal loss) flattered to deceive, no one paid much attention to those 40-50 minutes in which Real were toying with United. The problems resurfaced vs Stoke who were quite comfortable in midfield. It is too early to draw conclusions though. The picture will be much clearer after October when we play several strong teams. Maybe Matic + Pogba will be the key for a very successful season.
