The morale system in Top Eleven is upside-down. Win a match, and players who score hat-tricks or otherwise get higher ratings need their morale boosted before the next match. Lose heavily and all is right with the world and some players even gain morale...
I go into each match with all the players on 'very good' morale - if any are on 'superb' it's because they gained that status or I've had to use more than one Morale pack to get them up from below 'very good'.
