Physical condition

[sirgiorgio]

I'm currently playing as Juventus manager: first season, no Continental football, which means I usually have fresh legs, while my opponents often side tired/half injured players from the start, and sometimes they don't even take them off.

Is there a way to exploit this fitness advantage? Are there tactical instructions I can use, opposition instructions (I rarely use them, btw) or other tweaks I can use especially late in the game, because, ironically, that's when I struggle the most.

Thanks
