How big a squad are people carrying for 5v5?

With 8 or 9 available, I’d try to create more football rather than just manage a long bench. If the other club has similar numbers and you have space, two small games is ideal. Even a 3v3 next to the main 5v5 can keep players involved while they wait. If you only have one pitch, rolling subs can work, but I’d still be careful that “fair minutes” does not become constant changes every two minutes. At this age the guidance is very clear about equal game time being the priority. I’d look across the whole morning and ask whether every player has had a meaningful amount of football, not whether the starting five stayed untouched. Ten in the squad is manageable, but I would want a plan before kick-off rather than trying to remember who has been off longest.
