Sad day for football. Among all the great German midfielders since 2000, he stands out to me. I believe he deserves to be mentioned alongside the absolute best of his generation like Xavi, Iniesta, Modric and Pirlo.
From a German perspective, the saying "you never know what you've got till it's gone" applies to his career pretty well. Bayern underrated him completely so he found his luck in Madrid. He was scapegoated for the bad results of Germany and called "sideway-pass Toni" by German media, fans and pundits alike but after he retired from the national team, the performances detoriated even further. Until he finally returned under much applause. If he wins his sixth UCL with Madrid, making him the lone record holder, and manages to win an EC in Germany, he could even finish his outstanding career with a Ballon d'Or.
