The World Cup is underway and there's controversy on the pitch and off, particularly surrounding the sport's governing body FIFA.

As Joel Flynn reports the Switzerland-based organisation is one of the richest in the world and who runs it does matter. 

FIFA is made up of 209 national football associations, and last year reported annual revenue of nearly $1.4 billion.

For the last 16 years Sepp Blatter has been its president.

The 78-year-old has just vowed to seek a fifth term, promising to deal with a corruption row surrounding the 2022 Qatar World Cup.

But Blatter faces opposition from a growing number of officials, sponsors and players, who clim the organisation needs a new face.

Allegations were made about bribes in more than one presidential election, as well as questions about the bidding process for the next two World Cups.

But how can Blatter and FIFA change?

Soccer is already looking to the future - as growing numbers of nations look to bid for major competitions and bring football to their respective fans.

All eyes will now be on how FIFA manages that change.
