Self indulgent renamed player in your squad.

[Bluebird Hewitt]

Selling real players to noobs will earn you a lot of money. Simply rename your player to famous players and you'll start earning from noobs... Crap players named Lionel Messi earns a lot.

I'm going to try that next time and see if it works. I was hoping to get a bit more for the two players I sold, but both only sold around the market value.
