Speaking ahead of City's crucial clash with Ole Gunnar Solskjaer's side on Wednesday evening, the Spaniard revealed: "It’s important that the club is structured well, like here.
"But I won’t comment on what happens at United. This club in the last decade grew a lot.
"It’s not scary anymore to go to Old Trafford but we have to play at our best."
Victory would see Guardiola's men go one point clear of title rivals Liverpool.
"Four games left and we have to win our four games to retain the title.
"It is not an easy place to go but at the same time, it is a nice place to go. We know exactly what we have to do," Guardiola added.
Jurgen Klopp's team will face Huddersfield in a Friday night meeting at Anfield.

Guardiola admitted: "I expect the best United tomorrow, I am sure. They are proud.
"(We) prepare (for) the game as always, their strong points, their weak points and try to win the game."
