Exactly this. Aguero was completely shut off, Yaya didn't have a second clue on what was going as Kroos and Modric totally passed him into a spin whilst Fernandinho was running around trying to break up play but was left looking like a blind fly swatter.
The long and short of it is, De Bruyne is developing into a player of massive magnitude, he will have quiet games but he will have more good than bad and is already playing at very high level, both proven in England and Germany.
