It is very sad and a bit of a weird feeling also that he's gone.
It felt (or I felt, I'm not sure about that) a person like him would live for ever. He had this sort of "light" and "graceful" aura, and for decades success always seemed to fall into his lap: countless titles as a player (including captaining Germany to World Cup glory in 1974) almost immediately followed by leading a great German team to World Cup success in 1990, then Bayern Munich vice president, president and occassional interim manager (also winning titles as if it was some kind of God given right). Then high ranking German FA (DFB) official, bringing the World Cup to Germany in 2006. Always successful - and it always appeared effortless and the most natural thing to happen!
The last few years were hard for him: he lost his son to an illness in 2015, had to cope with corruption rumours with regards to the 2006 World Cup, and then he gradually became ill. In his last few public appearances he gradually came across more and more frail until they stopped completely. Still, it's strange that somebody who literally seemed to float above mere mortal things for so long is no more!
I'll miss him!
