You are right with your point once a couch starts disliking a good player not wanting to work with the player again and looking for a way to sell him out to other team know that all is not well there might have been a misunderstanding between the manager and the player.
If this player has been playing well, then he should not do it like this. We believe that his principles and words are in place, but a player who is playing well and is succeeding should not be treated like this with his development. It is good that he will get a chance in another team, but this player will continue to get a chance to play well in his own team and will improve his team. It may happen, but he should solve this problem and make a good decision with the performance and hard work of his team so that this mistake does not affect other players.
