Choose a player you want, then go to "Make Offer" under "Actions" on the player. Make a loan offer (must be 100% wages and one month). If he joins on loan, put him in the youth squad then select "Actions" and approach to sign him. He will then sign on a free transfer. Additionally, finish a season with a club of your choice then wait until July 1st. Then, go to "Player Search" and under "Contract Status" enter "Expired". Young quality players will be available for free.
First, choose your details but stop when you get to the team selection. Select Southampton and take control. Buy only three players of the same league and choose two friendlies, then continue with the season. You will then have the best team in the championship and will automatically get promoted.
Buy small, and sell big. Offer players to rich clubs, like in Spain and Italy, but put a high offer price for them. For example, with a 𧺬,000 player, offer clubs 㾶 million. Make sure you do not get greedy or no club will want them. Be careful when a new season starts and the new transfer budget is announced -- you will lose some of your newly required big budget, but not all of it. Spend heavily on quality players before this happens.
