Btw, I recently found out that you can play with 4 players (for example, Arsenal) until you try to make at least 1 transfer.
In theory, you can play at least the whole season with 4 players of one team.
You didn't say the most important part. That happens when you have a player from some other club (Eze) that goes to another club you already have 3 players from (Arseanl). You can play with those 4 players from that club but as soon as you transfer one of them out it is over
