There are a LOT of issues with spelling (Monchengladbach not accepted !), with clubs sometimes in their native language (Kobenhavn instead of the FC Copenhagen that everyone uses outside DK, same for Legia Warsaw or Prague clubs), some clubs need their complete name to be filled in (Bayern Munich, as if there was another club named Bayern ?), some require their city name ONLY (Salzburg - answered not accepted if we add RB or Red Bull). And seriously, 4 Saudi Pro League (that none cares about and only 4 russian, 2 ukrainian, 1 serbian or croatian clubs ? And what's the point to ask for the (quite) full elite of english, french, brazilian, italian, german or spanish leagues (full of minor clubs) while forgetting scottish league and a whole bunch of legendary squads in other leagues (Argentina, Russia, Croatia, Serbia, Czechia, Austria, Switzerland etc)?
This quizz could be far more interesting !
