Thanks for the link to the video.
I don't think there is any 'titty twisting' here but something was said, that is for certain. Whatever provoked Zidane, the video makes me think that his short run in front and then turn around indicates that he was provoked enough to 'want to hurt' his opponent. I don't think he turned from additional words said, but rather from the original discussion. Anyway, who knows until we get the actual story from the two players.
I haven't followed his career, but a player doesn't get to be a captain by acting that way over the years.
