Like for like. Yes good point. He's been playing a lot deeper than De Bruyne, Silva and Navas. Perhaps not fair to make a direct comparison. When he plays, he sets the tempo of City's passing. What you get with Toure is instant control and retained possession, but I feel it's in harmless areas of the pitch and his physicality is very poor. What I mean by that is that the highest quality games are played at such a sped that unless you have the baseline fitness, you can't make your technique count.
When I watch the best teams play, Bayern, Barcelona, Atletico I am struck by the sheer work rate of players when they lose the ball. There was a comment earlier counterposing energy with technique. The truth, I think, is that to be effective in the game now you need both. Toure covers his 10km per game by being in constant jogging mode but to be effective you have to be able to sprint repeatedly and that is what he doesn't do.
