The manager who won Germany the World Cup and Confederations Cup, whilst taking them to a Euro final and finishing third place in another World Cup? Just checking.
If I reflect over the whole time of Löw in charge...
2008 was quite ok, nothing special, but also no big mistakes by Löw I believe as simply the player quality wasn't there.
2010 was a fun tournament for Germany, just Spain seemed unbeatable that year and Müller was out for the deciding match - can happen, third place with this mostly young squad (most of them won the U21 Euros a year before) also is ok in my eyes.
2012 against Italy was just a massive tactical failure by Löw, playing Kroos to mark Pirlo was a recipe for disaster and absolutely on Löw, not on the players who where asked to do tasks they were not used to and were expectedly not good at.
The world cup 2014 was especially won due to being great at set pieces. These were especially trained by Löw's assistant (and designated successor) Hansi Flick, who had to argue together with the team against Löw that this would be important - so yes, this win was despite Löw, not because of him.
He neglected these areas again, got back to his narrow-minded ways and went on to fail in 2016 Euros.
The 2017 Confed Cup actually is the only tournament where I think Löw did a great job - took a kind of B-Team to that tournament, adjusted the tactics to fit this squad and they went on to win that thing. That was great work and here he showed that he is able to build a team and a working system with the players at hand.
He then went on to believe that his A-Team would be strong enough to realize his "vision" of football again and failed badly in 2018, neither was that team able to do what he wanted nor was he able to integrate the core of that 2017 team into his first team.
And now we have 2021, barely scraped through the group stage while so far playing a system that doesn't suit most of the selected players and Löw fails to recognise what's going on. Leaving Sane on the field for the whole match yesterday was just absurd for example. That's not better than 2018 in regard to the tactical setup, this is just a better team and fighting spirit, that alone won't be enough to win things. Löw still has a chance to fix his mistakes, but this again is so far a quite bad tournament.
As someone who has seen various "golden generations" flatter to deceive for England, I will politely disagree
Well, what is a "Golden Generation" in England? Looking at your history it has to be one that is able to win a Knock-Out match, we are not talking about titles when we are talking about England, are we?
All we have to do, is maintaining a good, 55yr old tradition of beating you whenever it matters.
