Automatic substitutions will keep the challenge equally fair for the full 90 minutes of the match. If one of your players gets subbed out, the player who gets subbed in will form part of your team automatically.
You will still be able to see all of the players' performances by accessing the player statistics. A new player card will be added to the end of your team's player cards displaying their individual performance. Additionally, the subbed in player will substitute the subbed out player in the Players' overview card.
