So using condition bonus means the players lose less condition? I figured they lose the same amount but will run more. I thought this because I have tried to save energy for the following match and used the condition bonus during the whole match, yet the players are exactly as tired/fresh at the end as when I use other bonuses.

Anyway, I tend to use possession bonus, as it appears to work better as a defensive bonus than the defense bonus. Barca used my possession/counter attack tactic pretty well against Athletic recently. Lately it feels like I can't score in tight matches before using the attacking bonus, though that's probably coincidence more than anything else.
