After having seen the Dutch team win their first group B match in the FIFA World Cup 2014, against the reigning world champion (Spain),
I was wondering what the highest win was ever against a reigning champion?
I searched all games for every defending champions from here. Spain's lose against Netherlands is the biggest lose for any reigning world champion in terms of goals difference (1-5). The second big lose is by West Germany who lost to France (3-6) 1958 world cup. It was a match for the third place. And it was the biggest lose in terms of goals against.
