Guardiola has admitted that he would not have been able to replicate the success he has achieved in England if it was not for the quality of players he currently has.
When asked whether he is the best coach in football, Guardiola said, via Sky Sports: "I was."
He continued: "Listen, what is the best coach in the world? I never felt I was the best, never in my life.
"When I won six titles in a row at Barcelona, and won trebles, I never felt that. I won because I had extraordinary players in the big clubs.
"There are incredible managers, they don't have these players, they don't have these big clubs. Give me a team that is not like Manchester City, I am not going to win."
