Different nets, different game

I am lucky enough to get a chance to play soccer 2-3 times a week. The only downside is that there is no consistency.  Sunday is 11-a-side, Monday is 7-a-side and Wednesday is 5-a-side.  It is hard to adjust to the different style of game each day and it is hard to improve as a whole.  Monday and Wednesday teach me how to stay on my feet while challenging a shot and my throwing passes. The thing that it does hinder is my 11-a-side strategy. In 5/7-a-side in some leagues the strikers can't come into your crease, but 11 man everything is fair game, these elements are also those that I need practice on are high balls and the ability to challenge the ball off the line
