I hope you not send your players with "poor" or "good" moral condition.
I know this moral also cosmetic or just visual but still we use blue to make sure our team has optimal preparation.
And again:
My point was, you send your team with "superb" moral, given max win bonus and win the match with 6 goal (0:6) and end of the match showing your team need another 13 blue to boost up players moral, no way, it must be bug.
