this is a bit of self indulgence mixed with a genuine question of "what would you do"

my son is a good sportsman, very good at football and rugby

He has been asked to go for trials at Man United and this starts on 29th September

between now and then he will have 2 football games and 2 rugby games and a number of training sessions

Im just praying he doesn't pick up an injury

do I hold him back do you think? with the rugby in particular?
