I think everyone does that.
What ways do you pick you squad.
Do you go on how well they have played in the last game or anything else?
I tend to pick the strongest available squad in terms of how fit they are.
Survival of the fittest.
I only pick players with 95% fitness + for some reason. I will only pick below that if I have a really bad injury crisis or I'm missing a player for a particular position. However, I rotate a lot so my team varies every game which means everyone is normally match fit and above 95%
