Great Britain's blind football team is hoping to win a medal in the Paralympic Games.
Currently ranked fifth in the world, the team has won silver five times at the European Championships.
The rules mean players must wear eye-patches or blindfolds.
The goalkeeper is sighted, but can't leave a certain area of the pitch.
There is no off-side rule and the football has ball bearings inside so the players can hear it.
Team GB have their first match on August 31 when they take on Spain.
