I train my players making sure this does not cost me any boosters, meaning:
- I set the training intensity to medium in order to avoid injuries. Nevertheless, this does not guarantee you won't get any injuries at all, (even in stretching), but it should decreases the "chances".
- I never over- neither undertrain my players. The purpose is that they are between 90 and 99% condition (and never waste 5% condition when they reach 99%) when they start their next match.

However, this year, I will have to go for friendlies for my B team as I am really short of morale boosters. A level 1 friend is my consenting victim for me to easily gain these 2 boosters + the daily booster he's gifiting me. Many thanks to him
