What is the biggest difference between futsal (five a side football ) and 11-a-side football ? The futsal pitch is smaller and the distance between players is closer. You have to make decisions faster.
In addition, there are no limit for substitution of players in futsal. And the player who has been substituted can go back to the match again. Goalkeepers need to throw the goal kick by hand only instead of using feet. Many players will stay inside the penalty area because there is no offside rule in futsal.
