Manchester City boss Mark Hughes is confident of integrating new signings Robinho and Pablo Zabaleta after the international break.
Hughes told City's website: "I don't see a problem, we are getting world-class players here and if you ask any club about bringing those sorts of players in, the effect is always positive. The guys already here will see it as a challenge, they will have to up their game.
"You have to regenerate a team to bring in new faces, it stimulates the group and bringing in the likes of Robinho can only be a positive."
