Squad size U13 with Covid in mind

Hi There

U13 and 11v11, we have a squad of 17 which has raised some ? Due to squad size for gave being limited to 16. During the return to playing friendlies back end of the season I found that out of 9 games 5 we were down to 3 subs, absence, Covid isolation etc.

I found that the bigger pitch and more physicality of the games meant the team really struggled.

a number of local teams are gobbling up players and are up to 22.

I want to continue to build the team to run until U16 so thinking of a squad of 20, I managed to give everyone 60 to 80% games time so 3 more players would mean everyone would miss a game a season if required.

what are you squad sizes and do you think it could work? Btw 3 times we lost 3 players at least due to isolation.

cheers.
