I'm more of a casual football viewer who doesn't focus much on observing defensive play or Chelsea matches though my (non-Chelsea-supporting) friend claims that Nemanja Matic is one of the best holding midfielders in the world alongside Bastian Schweinsteiger, Javi Martinez, Sergio Busquets, Arturo Vidal, etc.
How would any of you rate him when compared to other notable holding midfielders in the world?
