Normally, to get a largeamount of money in these games, you just have to take over another team with the "Add Manager" option and sell a player for an impressive amount. However, this results in having no players remaining, no transfer budget at your selected victim club, or even worse, the board keeps intervening. The solution is to take over the team you hate the most with the "Add Manager" option, as usual. However, instead of selling a player to them, have them put in a First Option bid for £100 million. Simply accept the bid and the £100 million is yours with no interference. No matter how deep in debt the club gets, the owners will not stop the transfers, and you can reap the rewards of unlimited money.
