Teams: F.C. Juventus of Turin
I'm not sure there is an ideal candidate out there right now, every top coach seems to a have particular flaw. Pep can't seem to crack the CL even with a stacked team, Klopp can't seem to win the league despite ample resources, Conte is too impatient and capricious, Mourinho has lost his touch, etc.
I'd say perhaps the closest to an ideal candidate from who's coaching currently would be Simeone or Zidane.
Simeone has proven he can do amazing things even with limited resources at Atletico, Zidane's track record speaks for itself, even with a very talent Real, they underachieved until he found a way to unlock their potential.
I'd put Pochettino a level below, simply because even if he's done brilliantly with limited resources, he's not been able to win a major trophy. And he's had his chances, like the year Leicester won the EPL, and the CL final this year. It seems he may lack something to get teams over the line.
