Actually, there is no fixed method to try. If you really want to change them into the team you want to play in the editor, then start the game. If you don't want to use this similar method and want to seek transfer from the progress of your existing gear, there are several points to pay attention to. First, your scout should be the best. Second, if your team is well-known, players in a certain position in your team should not have high ability values close to the players you want to introduce. This is what I summed up after playing for a long time. Another way is that although some players have a low signing rate, you can try to rent for one year, and the probability is greater than the transfer. In the year when he was loaned to your team, the chances of seeking his transfer would be great, and I did the same. However, the premise is that you have enough funds, the lease is expensive, and you have to pay the transfer fee.
