How will Nottingham Forest set up under Glasner?

Obviously we can't know for sure but is Glasner going to stick to his trusty 3 at the back formation or will he switch to 4 at the back? Who would be the 3rd centreback in the case of the former, besides Murillo and Milenkovic? Who will be in the midfield? Neco Williams is the hyped player but who is on the other side playing wing back?
