Dimitri Seluk has been involved in a public feud with Guardiola over his treatment of the midfielder, with Guardiola insisting that Toure will not play for him until the agent apologises for his comments.
However, rather than apologising Seluk has once again criticised the former Barcelona boss, who sold Toure to Man City during his time at Camp Nou.
"Pep Guardiola - he thinks only about himself. He thinks he is already God. He won with Barcelona many titles but Yaya also won the same titles with Barcelona. Pep thinks now he has won everything and he can do what he wants," Seluk told BBC's World Football Podcast.
"For me, very strange things (have happened) in Manchester City because Yaya played with them many years, (Joe) Hart played with them many years, I don't know, (Vincent) Kompany played many years, and (in) comes a new coach and says, 'Okay, these players out like dogs'."
Toure has made just one competitive appearance for the club so far this season.
