If you want to be rich, just go in as all the richest teams(e.g. Real Madrid, Barcelona, Valencia, Man Utd, Chelsea, Deportivo, Inter,) and buy a rubbish player from your side, with each of the rich ones, for all their transfer budget, then every player wants to go to a decent club so they will accept, especially if you offer them 100 grand a week or whatever! Your club will have earned over 150 mil by just selling terrible players!
