Bertie Vogts played in the first ever Bundesliga game I saw: Gladbach v Bayern and around 1978.. Also playing were Netzer, Gerd Müller, Beckenbauer, Stielike, Hoeness, Alan Simonsen, Sepp Maier and a host of world-class players.
As for the word 'Führer' it simply means leader and is used in many contexts that don't involve invading Poland
By the way, Münich in Spanish = Monaco.
The names Mönchen (as in Gladbach), München, Monaco are cognate with the English words 'monk(s) / monasteries'
