More transfer money
Use the following trick if your team is very short on money and you want to spend more. Create another manger, preferably at the start of a season as there will be more money available. Have this manager join a club such as Man City, Chelsea, Real Madrid, etc. Then, search for the club you currently manage and sell unwanted players to the new manager for very high prices. This creates high transfer funds and also gets rid of any unwanted players.
