Derby Manager tries to simulate a persistent football world. A world where clubs grow to great heights and fall on hard times. You might lose a game you were sure to win or even get relegated, but don't get disheartened, do your best to bounce right back up. Also, you can always take another club's hot seat if you're looking for a change.
In the beginning your money will mainly come in from winning matches. There is no one right tactic. Go through the post-match reports to see where your strengths lie and then look at the help section to see how to play to them. That’s also how you scout your opponents.
Formation and starting eleven is key to making your team play your way. Tactics have a substantial influence, but they won’t turn your 5-4-1 playing team into an attacking powerhouse. Test what works for you and adjust as necessary.
There is no prize money at the end of the season but you earn a bonus for every win so make the most of what you get. The win bonuses get bigger the higher you go, but wins are harder to come by. Sometimes it might be better to spend another year in your division to get a good squad together that would get wins in the higher division.
Your players are the heart of your club and it is of utmost importance to have a balanced squad. Don't underrate mental attributes! Older players won't be in your team for very long and their attributes will decrease, but they also punch above their weight price-wise.
Once you've decided to say goodbye to a veteran player, see if it's not worth promoting them to staff instead as they get a bonus to their skills. Staff is useful to focus your club on certain areas like training or finances.
In a similar vein, not every young player in your youth team has to be a potential superstar. Training them up and then selling can provide a nice boost to your income.
