Would we be better if we had a fully functioning Futsal system like the continentals all have?

Their kids can learn this game in tandem to proper football right the way through to professional level and it relies on people to develop their close control and quick passing skills on the ground instead of just their ability to get up and down a big pitch and heading.

We have five a side but that seems to mainly exist for older fatties to take up when their bodies won't do proper footie anymore.
