Cristiano Ronaldo is the most expensive player is the world?
There may be a more expensive cleat out there but if you are refering to American football and not soccer one of most expensive would be the Total 90 Laser II made for football.
It is Ronaldo.
The most expensive jersey has to be the throwback jersey of Bob Griese
its his first football card
kaka - 100million
