What is futsal?
Futsal is an indoor sport with similarities to football, though played with a smaller, harder, low-bounce ball. Teams are made up of four outfield players and a goalkeeper while substitutions are unlimited during the two periods of 20 minutes. The clock stops when the ball goes dead and players have a maximum of four seconds to play from dead-ball situations. Goalkeepers have the same amount of time to play the ball in their own half.
