Thank you @Russell Hammant

Okay, I understand that part about minutes and will keep it in mind.
What I've always struggled with is fixture congestion where I have 2/3 games a week over consecutive weeks and juggling playing time and I bet @MrPompey is probably in the same boat.
Generally, if a player is tired I'll avoid starting them but will probably bring them off the bench (match fit is usually the base). Still, players get upset about that - it's probably just down to the way I play but maybe put something in the AI to recognise team selection based on fitness, if you're tired you can't expect to start.
It's a constant cycle of player unhappiness.
