Is this the football tournament with the dirtiest challenges?

It’s as far as you can get from the pristine pitches at London’s Wembley, Barcelona’s Camp Nou or Brazil’s Maracanã.

Welcome to the Swamp Football World Championships 2015, held in Hyrynsalmi, Finland, from July 17-18.

The first organised championship was held in 1998.

The sport developed from being a training exercise for soldiers and athletes, such as cross-country skiers.
