I know one shouldn't generalise but I have always thought the German's poor winners rather than poor losers. To use a much quoted line, apparently spoken by a German commentator in 1999, when it appeared Bayern Munich were about to add a Champions League trophy to their already bulging trophy cabinet. There were of course only two minutes to go and Bayern lead 1-0 if you remember the match.
"And once again a German team has proved superior to an English team!!"
Of course he was wrong, if he ever said it in the first place, which was nice but it is that arrogance, that supreme confidence that makes our rare victories all the sweeter and the defeats, well just don't mention them!!
