Seeing as Yaya is Seluk's biggest client and main income source I think Touré really should be able to control what Seluk says. If he disagrees then it's easy to come out and say that. Touré should be the one in a position of power but it seems to be the other way around.
Looks like they've got a bit of a unique relationship. Yaya says he owes everything to him and sees him as a father figure. In his statement today Yaya has basically said he doesn't agree with what Seluk has said. Short of sacking him and publicly criticising him, which he'll never do if they're as close as it appears, not sure what else Yaya can do now
