I grew up watching Ballack play. He's great, no doubt, but I think his legacy is immensely amplified by the fact that he was far and away the best German player. Happened to play in the worst period of German football in the last 30 years at least.
For me it's
Kroos > Thiago > Schweinsteiger > Ballack
Thiago is the most talented, IMO.
Don't agree on Kroos being better than Ballack and Schweinsteiger (Thiago being better is an absolute joke). Ballack and Schweinsteiger are equal, very hard to separate both, but both have been better than Kroos because of their leadership capabilties. Ballack is rightly amplified for the exact reason, people say Germany was crap in the 00's but we still managed to reach two major finals and one semi-final. Why? Ballack! So many great moments, the whole of the 2002 WC, his performance v Argentina in 2006 where he played on one leg all of extra time, and then went forward to score a penalty, the goal against Austria to take them into the quarterfinal at Euro 08 (followed by another goal v Portugal).
I'm not even going to bring Thiago into this conversation because he has no right to be in the same breath as the other three. Thiago has certainly been great lately, but Kroos and Schweinsteiger have been at that level for years now and have won trophies at the national, European and World stage. Ballack, while not having the same success, was at a higher level for most of his career as well.
About talent. I'd say Kroos is the most talented out of all named above, he could play at a world class level both as an attacking midfielder (under Heynckes at Bayern) and as a deep midfielder, where he currently plays. He has the ability to dictate play from deep and score 10+ goals a season consistently (something Thiago has never shown in his career). I've always said that Kroos has never fulfilled that talent because he was shoehorned into a deep midfield role, when he could've been one of the most complete midfielder's in the world with his ability to come deep and then move forward to score goals (like he played under Heynckes).
In my filter bubble around my regular seat in the Allianz, all occupied by decade-long season ticket holders, the verdict on him was about 50-50. For Kroos it was about 40-60 ("Rückpasskönig"), even for Schweini, it was maybe 70-30
Yea I remember in 2006, when it was decided that he was leaving for free, I think Hoeness (or Karl Heinz) came out and said he wasn't good enough in the big European games (he then followed up and scored a worldy against AC Milan
). There was a lot of animosity from Bayern fans that time when he left for free. That is understandable, to see your best player leave the club and you get nothing for it.
