Sorry if this is in the wrong section.
I am keen to find out if anyone has heard of a training method that I understand Barcelona use. I sure other clubs use it too.
Apparently they divide the field into 8 or 9 grids. When one player moves out of one grid another has to take up that space. I have tried to find it on the net but had no luck.
Would be keen to know if anyone has heard of it and can post it here?
