Mine are, in no particular order:

Ed Moses
Muhammed Ali
Usain Bolt
Franz Beckenbauer
Rivelino

Being a big athletics fan I was tempted to include Lynn Davies, Jonathan Edwards or even Seb Coe as my last pick but in the end I went for Rivelino, who I was enthralled by during the 1970 World Cup and just couldn't leave him out.

Unless their personality appealed to me, I dismissed certain sportsmen, no matter how dominant they are/were in their field. Both Tiger Woods and Lewis Hamilton come into this category.

It will be interesting to see who your personal favourites are.
