Goalkeeper Joe Hart travelled along with Willy Caballero, who was preferred to the England keeper for the 2-1 win over Sunderland, as well as youngster Angus Gunn.
But Guardiola would be not drawn on reports that Hart could be set to leave the club to be replaced by Barcelona's Claudio Bravo.
"Since I have been Manchester City manager and we have been together, Joe has been perfect. He is a great professional on and off the pitch," Guardiola said of Hart.
"It is not the moment to talk about players who are not in Manchester City and in another club. I won't talk about transfers before such an important match in our season.
