I get the feeling that he likes Nacho too.
I might be imagining things but he seems to be sick of the almost there nature of Sterling and Yaya and even Aguero (yet). When the other players become crisper then I think we'll see even more from KDB.
Put it this way, had he signed for Barca, Real or Bayern he'd be talked about as the most likely next "best player in the world". Not just because of the club status but because those around him would make him shine with more consistent passing and movement. We are not at our best this season so are actually holding him back I think. I can't wait for us to click but it means Yaya, Sterling, Bony, Aguero, almost everyone raising their game together.
In the meantime I think KDB has definite favourites who's qualities shine through like Nacho and Silva.
