High pressing + man to man cause extra condition loss.
So, after a game with low press and zonal you loose about 20-22% condition and with high + mtm you loose double.
Use them for emergency, when you 're desperate for a result and not from the beginning of the match.
With this way you 're saving greens.

Also try to buy some more 5* players.
Go for 80-85% quality, not young. They are cheaper (money and token).
