Africa has the fastest teams, that's for sure. There are other factors that go into a team's success other than region, I definitely said speed is an important factor among others right?

Where is your evidence they have the fastest teams? I'm asking for evidence, please, not repetition of claims without data.

It's not scientific, or even representative, but watch the recent Senegal vs Poland world cup match.

I think Poland was the #4 FIFA ranked team. Wow was the athleticism gap pronounced for Senegal.
