It was rating of that players in the game: 5
If a player gets bad ratings 2 or 3 games in a row, put it on the bench.
Friendlies against weaker teams is also a good option to improve the moral of yours players

It happens to everyone those kind of results, but sometimes those also happens in your favor, so just forget it and try to do better next time.

I always try to have my players between 95 to 99% before the match, but i already played games with condition bellow 85% and won it.
I just think that bellow 85% will increase the risk of injurys or a come back of the other teams in last minutes, because of tired players.
