to be honest, Malaysia's futsal has a lil change of face .
The real rules :
There's NO PUSHING nor ROUGH UP TACKLES between the players.
and
there's a 6 fouls violation for each team. Once a team commited 6 fouls, a penalty will be given.
A red card doesn't actually sends u off for the rest of the game. But suspension of total  5 minutes.
Passing back only to ur goal keeper if ur the last man behind, else it's also considered a foul.
but i dun see all these rules apply on any community matches or league games zzz

I play for a local state futsal team , and i find the rules are so so much different from the original ones.
There's a good example when KL hosted the KL-5. A slight push is considered a foul ( the trick is to go beneath the referee's eyes )

Erm , if ur playing as a keeper, dun mind  to dribble up and pass the ball, u make more options by doing this. And local futsal courts are way too small for tricks

Anyway , every team needs a player who can take on defenders. Every team needs a Falcao.
