Set a player in the transfer list for
999999999, and in a couple of weeks a
team will buy him for that.
Raise the pay of one of the coaches to $999,999,999 per
week. Then, offer him a new contract. The coach will now
want a contract for approximately -$14000000 a week.
Accept the contract to receive that amount in your account
Replace the first two digits of the price with zeros when
players cost more than $23,000,000.
Rapidly improving players:
Do not buy any coaches, but still select players to train as you usually would if you had coaches. The players will improve the selected statistic by one point each week, and youth players will improve even faster. If players are left training on this statistic when they reach 99, they will keep improving to numbers over 100.
