It's gutting but what can we do? Literally the only thing we can do is trust that he'll be replaced with similar quality. There's no guarantee in that of course, but there are hundreds of thousands of professional footballers in the world so there's plenty of opportunity to find someone decent.
Pretty used to where we are in the food chain now..
Klinsmann played a HUGE role in the restructure of German football, especially the youth structure post-2002 World Cup. And led a transitional side to the semi finals of a World Cup. And has a win rate of nearly 60%. And his a global/renowned name. Don't know anything about his style of football but he doesn't sound too bad to me.
