Not sure England could've got someone better than him, other than maybe Pep being the obvious candidate that fits the "better" criteria.
I hope Tuchel brings the likes of Rashford, Mount, Sterling, and Maguire back into the England squad to play important roles...and I think he rightly will.
Also, you can trust him in my opinion to find an optimal team balance, after all the unbalanced teams Southgate kept trying to make work in international tournaments, and he will make big, much needed changes to the team:
1. Phase out Pickford for a technical goalkeeper
2. Have Trent as his nailed-on right-back
3. Pick pacey CBs like Branthwaite and Gomez who are able to cover big spaces quickly, next to your Stones/Maguire/Guéhi/Colwill types
4. Rice needs an expansive passer next to him. Wharton fits this description the best IMO. I expect to see him play an important role as well. I also wouldn't be surprised if he used Bellingham much deeper and give Palmer a go at #10 instead.
5. Don't start Foden again when you have comfortably superior profiles and players at both wings and at #10 too. First name off the bench as an impact sub is what his optimal role should be for his country
