Think we should simply forget then meme of "Busquet's role", "Xavi role" etc. The future midfield will be different in nature with entirely new roles. Trying to shoehorn every future player in a role from our classical team isn't constructive. I think Arthur and De Jong have some similar traits and some that would complement each other, but they are not as different as Xavi, Iniesta and Busi were with each having very distinct role. Maybe they can play as a double pivot with Coutinho as an AM/SS in front of them. De Jong would probably be in more advanced role as he has already proven to be good at driving the ball vertically forward and keen on giving line breaking passes. Funny, he seems to be even almost keen to do them, even when as simpler approach would be more productive. Backpass merchant and forward pass merchant would be nice balanced combo and they are both good defensively. I'm tired of this idea that we need a "baby sitter". Those two will be beasts at high pressing so we shouldn't have to hope for 'new Rakitic'. I hope we never need Rakitic type of player. Everyone should be fairly good at defensive duties and intense pressing needs to come back.
