How do YOU use substitutes?

[Eugen Cristea]

I sub any player that receives a yellow card immediatley.
If i'm not winning, and i don't see the name of a player in the comments, and he usualy is there, i sub him.
And i also sub, if i have to change the formation, and don't have the right player on the field.
I always leave a sub untill the 81 minute, and then i make the 3rd sub, usualy subbing the good players, so no troll injuries happen in the 89th minute.

Similar to how I do it. I usually sub off anyone who has a yellow card, though maybe not instantly, if they get it in the first half I wait until half time. If they get it in the 2nd half I take them off straight away. If my opponent is really tough I try not to make 3 subs because usually I end up conceding. I just tend to replace 1 player who isn't playing well and throw on another striker or an extra defender depending on the situation.
