Decide which player you would like, once you do that go to Make Offer. Make a loan offer; remember it must be 100% wages and one month. If he decides to join on a loan put him in the youth squad then select Actions and proceed to sign him. He will go ahead and sign on a free transfer deal.
To make easy money all you have to do is,
1.Pick a rubbish player that has a little value
2.Go to offer to other clubs(on you selected player)
3.and offer him but for much more money than he is worth and teams will bid and walla!
