See I don't think it is necessarily that important to have a high morale and condition on your players.

In My first cup game today against a stronger opponent my players were all at about 45-55% condition and ranged from 70%+ in morale yet I won 1-3.

I think there is more importance on formation and tactics than anything. I often wait til my players are the lower side of good in morale until I boost. I'm not made of boosters. :-)
