You say your morale is very high at the moment and
i presume after another big win even if you praised your team morale would'dt go up anyways with it being superb/very good.So like Frazt say's dont concern yourself with it.If the majority of your team have superb morale and only one or two have good/very good but are playing well then try praiseing them through the media, you will
prob find there morale will go from very good to superb through that.
