Player reaches next star, following game he sucks

[Gert Funck]

yes, good point. I still remember when I 've lost in a Cup semifinal in lv3.
I trained my players (most of the squad) 3 times, 3bars practice, gave them greens and then they performed unexpectedly bad in the afternoon game.
Also, if you have some gathered sp and give them only in one skill (attack for example) then it can change the balance of the player (some times for good, some times for bad).
but in general, no for me.

So what your both are impying is that they need som actual resting before the game, eventhough they are at condition 95-99? how long would you recomende?

if this is true I need to tweak the way I traine my team
