Absolute dream world: Simeone
Possibly realistic and might be decent choices: Ten Hag, Gallardo, Favre*, Emery? (Given what he's done at Villareal)
Could probably do worse, but also could probably do better: Potter, Dyche
Back-up choices if everyone else turns us down: Moyes, NES, etc.
Please God no: Howe
* Favre looks good on paper, given his work at Mönchengladbach and Nice and early on at Dortmund. And he's available currently. He is willing to give opportunities to younger players, too. But his tenure at Dortmund flamed out pretty hard (basically a repeat of these last few months with Ancelotti - losing inexplicably to lower-level teams, having trouble keeping the team motivated, etc.), and he's already 63, so how long would he really stick around anyway?
I just can't see Conte here either.
