Video: Mexico's Omar Arellano poos himself on the pitch

Dirty play

USA v Mexico matches are serious business. They stop for nothing – not even a toilet break.

In what was Jurgen Klinsmann’s first game in charge of the USA, Mexico winger Omar Arellano decided to, erm, mark the occasion in pretty disgusting fashion.

The Guadalajara man had a bit of an unfortunate accident during the match. He might have got away with it, but for the unfortunate fact that Mexico play in white shorts.

His stained shorts were spotted by the TV cameras and now the world knows his dirty secret!
