While not strictly PC, in euro footbal circles we split the three into Fat Ronaldo, Ronaldinho and Ronaldo (Christinao Ronaldo). Fat Ronaldo because he got fat when he retired, Ronaldinho because thats what his shirt said when he played for FC Barcelona, and just Ronaldo (Christiano Ronaldo), because he is the current one.
"Fat Ronaldo" is a little unfair--he played for the last few years of his career with an untreated thyroid disorder. It was left untreated because evidently levothyroxine is a banned substance since it can be used for doping.
He was a sight to behold. At least 5 kilos overweight (as a professional football player!) and he could dash in front of defenders in front of him. I saw him 2-3 meters behind a defender during a 10-15 meter sprint where he ended 2-3 meters in front of the defender at the end.
