Because I've seen some managers already started to open some threads because they can't find some simple information about the new feature Associations I made a thread with the most popular questions so far.

Question: How can I leave an Association?
Answer: To leave an Association, simply go to your Association Overview ( my Association > Overview), open Members tab and click the icon you will see next to your name. Members who take part in Tournaments can't leave an Association until the Tournament is finished.

Question: My players will lose condition or moral?
Answer: Your players will recover after Tournament matches so you don't need to worry about condition or injuries, they will be exactly in the same condition and state they were before association matches. You will see your players' condition going down as usual during Associations Tournament matches, but after the match the level will return to the exact state it was at before.

Question: What condition and moral my player will have when the tournament game will start.
Answer: Players will enter the game in the same exact condition and moral they currently have, and after the match they will keep having the same exact condition level.

Question: Can we win some rewards with the Associations?
Answer: Yes, there are more rewards that you can win from boosters to tokens. More details you can find here.

Question: When we can play in the tournament?
Answer: In normal weeks (not end of Season weeks), Tournaments happen in Saturday and Sunday. uring the last week of the Season, Associations Tournaments will happen one day before: Semi-finals in Friday and Finals in Saturday, to avoid the kind of problems you mentioned (players out of contract, players losing stars, etc).

Question: Can I join more Associations?
Answer: The answer is no! You can be only in one Association.

Question: Can I loan a player for Cup, Champions or League game?
Answer: The answer is no! The loaning system is working only for Associations tournaments.

Question: How many substitutions I can make per game?
Answer: Is same like for all official games. Only 3 substitution per game.

Question: How many players I can loan?
Answer: You can loan up to 3 players. Here is a special guide and all you need to know about the loaning system.
