In terms of where we go with this, I think the obvious choices would be Antonio Conte, Pochettino and NES.
The former for very different and obvious reasons than the latter two.
Firstly, I feel one of Conte or Pochettino will be available to us depending on which direction Spurs go.
Conte will bring the razzle dazzle big name pull to sign a ready made higher calibre player instantly that I believe Moshiri wants.
However, I believe from a Brands standpoint, NES and Poch would be the direction to go. Both have shown evidence of being able to achieve targets with a longer term recruitment plan.
Personally, I would go the Nuno route. His achievements in guiding Wolves to the championship title with a big turnaround in players and then qualifying for Europe is exceptional really. With a bigger budget I could see him getting us top four over a couple of years building a squad.
Ultimately, I believe they will land in the middle ground of big name and proven squad builder with Poch. Though I feel his ceiling has been proven with Spurs and NES' is possibly a touch higher in that he might win us a trophy.
