Great thread.

I play the pivot position in my team in the diamond position. 1 thing i demand from my teammates is movement. Always get into a good position to receive the ball. Help me out. Don't stand behind an opponent as i cant pass the ball through him. Get into space and i WILL find you.

Random tips:
Make diagonal runs. Look up. When in doubt, stop and pass it back. Run for your team. As have already been said, sometimes if you are inferior to other teams in terms of technical abilities and skills, beat them using your athleticism.

I don't recall seeing anyone posting about the use of your body for a defender when defending. Well this comes from my background of being an outfield player first but your body is very important even in futsal. Leaning into another player almost always makes him lose his balance and thus miskicks or mis-control. Im not saying bodychecking but applying very minimal pressure on someone's side is very effective. Also important when shielding a ball when letting it roll out of play and also when holding the ball up front when waiting for support.
