I reckon he's going to play holding DM with both full back bombing on and Maguire and Varane moving wider and level with him, rather than him dropping back. He'll also be the one to provide the quick long ball as opposed to de Jong dribbling out, so we'll always have options when playing out.
I think the defense will step up as a group and push really high, fullbacks becoming auxiliary wingers, a bit like the dippers.
DM is a possibility and I can see the potential in what you've said. The one thing I will say is that our fullbacks were tucking in quite a lot against Liverpool, in front of the CBs. How this will influence his role remains to be seen, unless an Ajax fan can comment. It might create a hybrid CB/CM type role for him. Depending on what ETH likes to do with his tactics.
