I think you're kind of right, but every team need a nuisance in front of defence at the moment and he's been the best in the league a long with Kante at the moment in doing this.
The game will change again in a season or two and may require someone more technical - which Schniederlen and Davies may offer.
Hell, how many centre-mid defensive backs do we have? Morgan, Tom, Barry, Besic, Macca, Gibbo, Cleverley.. are we just the PL repository for unwanted Greater Manchester defensive midfielders (5 of the 7)?
