In the ‘Team Room’ area if you click on ‘Team Sheets’ you can select from all players in the squad.
Once there, click on ‘Add a New Sheet’. You can then drag and drop your players from the squad section into the ‘team sheet’ in any formation you like. There is also an area for you to identify who your substitutes will be. The sheet will automatically save, leaving it up to you to publish at the appropriate time.
