Of all the stories emerging from the corruption scandal now engulfing Fifa, one of the most spectacular must be that of Chuck Blazer, a member of Fifa's executive committee until 2013 and now reportedly the source of some of the information allegedly implicating a host of other Fifa grandees.

There he teamed up with Trinidadian football administrator Jack Warner to engineer Mr Warner's election as president of Concacaf in 1990.
The two moved Concacaf's headquarters from Guatemala City to the US; it was at this time that Blazer signed a contract with Concacaf that entitled him to 10% commissions on all sponsorship and TV rights deals through his company Sportvertising, giving rise to his nickname of "Mr Ten Percent".
