I think De Bruyne shows you the benefit of playing for a great team, for example he done very little against Madrid in their last game, 81% pass success which is decent, 31 passes made compared to Kroos with 56 or Modric with 49. Created may be one chance and spent most of the game fading in and out on the periphery at times, until he scored his goal. When you play for a great team it allows you the platform to cruise, until the right moment, and when the right moment comes you still get the praise.
I didn't watch that Madrid and City game feeling De Bruyne was the best midfielder or the best player on the pitch, that was Modric and Vini for me.
De Bruyne making 31 passes at 81% pass accuracy is not a vintage midfield performance.
