Auto subs - How does it work?

[Rob1984]

It's used so that injured players are instantly replaced if you are offline.

It's a bit confusing at first but the players you put into the slots are the ones that are subbed off, the game will randomly put another player on, it's not one slot for the player going off and the other for the player going on.

The best thing to do is make sure you are not left with an illegal formation if one of your players are injured.

I thought the slots were for players being subbed on. E.g. In your substitutes you have 2 MCs, then put them both in the midfield slots. Then if a MF player gets injured, they will be replaced by one of these two players.

EDIT: Just watched the tutorial video and you do select your spare players that you would like to be subbed on as the ones that go in the slots.
