Ive been saying long time now that he belongs into that list we cannot reach. Top of pipe dream list in my personal opinion.
In a way he and Sevilla is like Raineri Leicester. ...they found the ultimate winning formula.
It will be De Boer or Koeman. Last mentioned is my preferred choice. He just ticks so many boxes. (Not even a whisper after theyve negotiated, it's clear sign, he waits our nod)
If Moshiri is as ambitious as we think then we have to be going for the very best. Personal preference aside that would be Mourinho, Simeone, Emery. We've had discussions with Jose, Simeone's going nowhere (but we should check) and we should be contacting Emery. If all of them say no then you move on down the list, if we do that and end up with De Boer/Koeman thats fine, if we don't do that and end up with De Boer/Koeman not so good. For me it's about aiming as high as you can, the failure is in not doing that.
