1) What happens if I active every substitution for suppose at 60' , which one will take place as I know there are 3 sub limit ?

2) What happens if an injury takes place after 3 subs completed or a substituted player gets injured who will take his place?

2.1) For example I use 4-4-2 formation and I subbed both of my SC , and a substituted player gets injured who will take his place?

3) If 2 players are subbed already at a fixed time for example 30' and then a player gets injured at 43'  will the substitution at 60' take place or the injury will count as a substitute and sub will not happen?

According to my information, the answer to 2nd point is your team will play with ten players.

3rd)60' substitution won't happen then

It would be nice to be able to follow the game and interact as it happened on GoalTycoon
