#4 Top to bottom strength
That experience, Löw taking a young squad to the Confederations Cup and even more youngsters prevailing at the youth championships last summer, has converted into unrivalled squad depth.
No other country has as many viable choices as Germany, who could pick no less than four separate, reasonable starting XIs for the competition.
Unfortunately for Löw, the 57-year-old strategist is just permitted to take 23 players, of which three will be goalkeepers. Choosing a balanced squad from the wealth of talent at his display is Löw's major pre-competition challenge.
For Euro 2016, he left out Marco Reus, Julian Brandt, Sebastian Rudy and Karim Bellarabi – who will pass up a major opportunity this time around?
