Partially agree but not with your priority ranking.
In my eyes the quality CM ist absolute top priority because that's the weak point and thus the reason for our instability in defence. In my eyes we need rather two than one new player there (Moutinho and Medel would be my preferred targets for a new CM but unfortunately not realistic
)
Second priority has to be the man for the wings because right now we have exactly zero constantly good playing wingers. Optimally a player to add both creativity and speed to our midfield. We have been linked with Rafa Silva of Braga lately who is a quite Hazard-like type of player. Yannick Ferreira Carrasco might be worth a look too.
Striker at priority rank 3 and CB at 4.
