Yaya has apologised and Yaya can't control what his snake of an agent says, so that should be the end of it
Pep should accept the apology and say that Yaya is back in the squad. Can't really see him ever commanding a starting place in the team though
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.
