De Bruyne was widely viewed inside the club as a likely successor to Silva going forward. I have been of the opinion since early in his tenure that he really has more similarities to Toure.
The misconception about Yaya is that he makes (rather, made) those unstoppable bullish runs through the midfield, tearing the opposing line to shreds. Yes, he did that on occasion. But the guy had an almost supernatural ability to keep the ball, find the right pass, etc.
This is what I have most noticed about KDB and lines up with a lot of what you write here. Good article. Very exciting player. Would look forward to matches last year just to see him play (and there was little else to look forward to for most of that campaign.)
