two outside lanes play press and cover, with goals either end. Focus on team out of possession and good pressing from 1 player with Smart Cover from the second player.
Players in middle can play 1 v 1 to start & can move players between games for a good mix.
After a few rounds, players in middle become wall players for attacking team so now the team defending need to think about how to defend against 3. In particular looking for 1-2's with wall player and how defenders think about the space and risk (stay 2 v2 in box, go zonal..)?
