Well, would not say any German team underdog in European competitions. You have there in Germany many good players and strong competition between teams (except Bayern, of course). So, your teams are winning European trophies, regardles it is matter of Bayer, Borusia, Stuttgart, Eintracht, Cologne, Werder or Hamburger ...
Cologne is not far away from Frankfurt, so pretty cool you are happy with their success!
We had great matches with FC Cologne couple of years ago with my FC Red Star :top:
