My opinion is that we should limit the friendly matches, so that the game can not start without my permission, not that anyone intentionally or unintentionally to schedule a friendly match, and play the same, and my players are tired or injured. I had a situation where a friend of mine from ignorance played two friendly matches with my team, just before the match in the league, that was important to me (I was fighting for the first place) and the result was two major players were injured, and the other is exhausted. I hope that someone will read this suggestion, and the game introduce such restrictions about playing friendly matches. THANK YOU
