How can one trainer of lvl 6 be so much better than another of lvl 5 justify this amount of money?
One quick answer may be people who want to train players for their National Team. Any increase in training will help their country in the long run.
I am likely to dump my players, demote and start training only U21 and NT players after I pick up a level 7 coach. I won't care anymore about how much the coach costs since I don't care too much anymore about how my team performs.
