can as well be seen as the obvious. Information is key as the media will always want information because be it good or bad they are going to make money out of it and that's what matters the most to the media at the end of the day, they always want to stay relevant in their space and one means to stay relevant for the media is getting more information regardless of what it is.
The media will stop at nothing to get every possible information to maintain and gain even more traffic. ETH should know better and try every possible means to avoid the release of too much information than necessary to the media, cautioning player to follow suit aswell will be a good idea. Dress room talks especially one's with some level of negativity should stay within the team and in the dress room.
The owners of the team sometimes seem to interfere much more than needed in the affairs of the club, this can be seen in some cases where they may want to make choices of players without much concerns as to if the coach approves of it, I think it's of utmost importance that the coach be given some level of independence especially when it has to do with choice of players because he will be the one to work with them most of the times.
