It is quite funny with all these rituals of fitness cards after every game, subs at half time etc.
I go in to each game:
1 gold player on the bench; Musa
Unless fitness drops below 85 on any player I just play, a lot of my games go to ET. Stamina is always enough to get me through the game.
I only make a sub when at full time and that is just Musa obviously.
