Despite being renowned for his ingenuity and tactical ability, the Argentine believes many of City's tactics are a mystery to him.
"The argument I give to explain my respect and admiration for Guardiola is that the beauty of the play of the teams he built you can't copy," Bielsa told a press conference on Monday.
"Guardiola builds alpha teams.
"We always said 'what would Guardiola do without the players he had in Barcelona?' and you can say the players of Barcelona are unique. The players of Pep Guardiola's Bayern Munich are very good and Manchester City too.
"But the capacity to create a style which you only see in the teams of Guardiola is much more important than the players he has.
"I'm not saying the players aren't important. I'm underlining his capacity to be creative. The things you can't analyse are a mystery for those who don't know about them.
"When I watch Manchester City games I feel I'm ignorant. You have a picture where 10 players are in front of their own box and City move the ball, trying to find the space to put the ball in. I see what is well done and try to copy it and understand it. But you can't copy Guardiola's teams.
"When I see it I'm wondering 'what's the method? What do we have to repeat to do that? What are the pre-established needs to solve this compact defence?' But you never find out. They always find a solution."
