I’ve got a player that can either play on attack and/or defense. But he is been displayed on the attackers list, how do I put him on the defenders list???

go to the player option, there u see a blue icon with arrows that says “swap”. click on it and he will change.

Player option?

Do you mean on team set up? Or on “players” ? Sorry, Im still not finding it.

Vaugh means the page with the player info. By clicking on the player in the playerslist you get the player info page. There you can swap the position by clicking on the blue arrow icon after the position of the players.

Got it !!!
Thank you, Gracias, Obrigado!!! :D
