It has to be either;
Tuchel - who got Mainz to their highest ever finish on a shoestring budget and took Dortmund to 2 German cup finals vs Bayern, only lost the 1 on penalties vs Bayern. His style of play is similar to Guardiola's actually, our attacking play and players like Martial, Rashford, Pogba etc would flourish under this guy. A bit defensively naive and he needs to iron that out though, perhaps the break from Dortmund has given him time to do this.
Jardim - Not only gets the best out of young talented players, but the older ones to, beat out powerhouses PSG to the League title and even got Monaco really far in the Champions League. Could do wonders with an actual budget. Almost a no brainer really.
Now these are risks of course, but a risk i think we should actually take. I'd love to see Pochettino as well, i just don't see him leaving Spurs anytime soon though, i think he's building something there. I think these types of managers are the future of football, they are cropping up everywhere and are coveted by big teams, the Ancelotti's and such have had their day. With these I think we stand to have a great future, provided any issues on club and board level are sorted out, like perhaps the appointment of a DOF for starters.
