I wonder if Mourinho would change a player like Fabio Cannavaro to defensive-midfielder because of his sub 185cm height. We all know he would never have had the sheer audacity to try Cesar Azpilicueta [a career fullback ] at the centreback position. Actually it seems to be a career hallmark of Jose Mourinho to play defenders at defensive-midfield. Javier Zanetti, Pepe, Sergio Ramos, and Fabio Coentrao, all have played and failed (except Zanetti) at defensive-midfield.
