Thank you all for the replies.

There are rests, I can earn them by asking friends for gifts but I can only get one per day. Also if one training per day is not enough, I can train them alot but my players will lose condition and also lose matches.

Also I have a question, what should on Set team intensity for First Squad and Substitutions and reserves? Which kind of training should I give them everyday and how many trainings? When? I also need to level up my players badly because most of them are only 2 stars now. At this rate I will lose every match and will get demoted.

Another question: Are legendary players on this game that played this game without spending money on tokens? Because I really like this game and still wants to play it. But I can't spend money on tokens.
