OMG!!!! My advice to u mate, fire him asap. 168k per week is ridiculously expensive. I saw that u only started playing this game about 2 weeks ago and in division 5, advanced trainer is sufficient. Obviously it makes sense u got him for 1k because his salary is sooooo expensive. I'm pretty sure that your weekly net income is like...-100k or more. If u don't fire him asap, your team will go bankrupt and u'll have to start this game all over again.
1) Fire the trainer (or buy an advanced or competent level trainer. I got advanced level trainer for only $5000 week with 15,000 salary which is pretty cheap) and if your PR manager and doctor's salary is more than 20,000 each, I say fire them as well and find much cheaper PR manager and doctor.
2) U have 19 players which is too many, sell 5 to 9 players. But leave the young ones and sell the other ones, as u can train the younger players. (I only have 10 players because 10 players is enough for me and having more will only reduce your weekly next income).
I believe u're in debt already, so act quickly so that u don't lose your team.
