Premise: The 2007 Ballon d'Or, given to the best football player in the world as judged by an international panel of sports journalists, was awarded to Kaká. This was the first year in which players from clubs outside of the UEFA federation were eligible for nomination; this change also led to an increase in the voting pool to include journalists from outside UEFA countries.
Hypothesis: Kaka was happy with being given the Ballon d'Or.
