Plushenko is a blabbermouth. There was no reason for him to divulge such a conversation. Just like there was no reason for EG to divulge that conversation she had with Zhenyz about keeping Alina in juniors one more season.
Agree the coaches need to learn to keep their mouths shut. I even wonder if they made up / distorted those comments they "reported". I wouldn't put it past either one of them.
