Obviously there's many ways to measure influence, but Franz Beckenbauer is worth a shout:
- As a player, one of the all-time greats
- Invented the libero position
- Also played in midfield with great success
- Captain of the first national team to win the Euros and the World Cup consecutively
- Captain of a Bayern team that won three consecutive European Cups
- Manager of World-Cup winning West German national side
- One of three people to win the World Cup both as player and manager
- Chair of Germany's winning bid to host the World Cup (yes, tainted by corruption)
I'd still give the nod to Cruyff, though.
