Lol go back to playing FM please.
RB - TFM.
CM - You need a ball winning midfielder to anchor while Matic holds and Pogba roams. Herrera is very good at that role, plus TFM can do well in that role. We do need to add depth with Fellaini & Carrick leaving.
No. 10 - Um if we play Pogba in a midfield of 3 you don't need a no. 10. Plus we have too many central options already with Mata, Mkhi, Lingard, Martial, Ibra who all can play that role if needed.
CB - We have too many already. Rojo, Lindelof, Blind all fit that BPD category. But with a 4-3-3 don't think we need to rely on it as much so Jones - Bailly pairing will be the best defensively.
ST - Rashford and Martial are both naturals strikers we don't need any more. Jose just needs to be willing to sub out his striker, something he didn't do with Ibra last year, and certainly hasn't done so with Lukaku.
We need a superstar wide forward, a young winger, one experienced midfielder, and one young high potential midfielder. Recall TFM, Pereira. Sell deadweigt in Darmian, Blind, Mkhi. Maybe take a punt on a young attacking RB since I think both Valencia, and TFM are more defensive FBs. Though you can just play Ashely Young if you need a better crosser.
