What condition is good enough for a good performance?

[Tyltyl]

I use to do that fear my team might lose and blame on condition & morale but not anymore. As long as my player condition can last through out the game then its fine. Ever experience a player scoring goals having good rating but morale still down after game. So dont bother abt morale just bull****. Now i dont blame on codition & morale just the game engine.

Same here, but I went to full superb preparation straight into bad defeats more time in latest seasons, while I won without caring too much about it.
Do as you said, just go with enough condition in order not to run into injuries.
