Europe is footballs power continent no doubts.
But stil... This is the number of WC berths for continents:
Oceania 0,5 / N.America 3,5 / S. America 4,5 / Asia 4,5 / Africa 5 / Europe 13
I'm sure if any continent was given 13 spots, despite their strength, they will have easier time, making it to the knockout. simple mathmatics.
