The departing Malaga coach is expected to be named City manager in the coming days.
Zabaleta said: "I have never worked under Pellegrini before, when he was at San Lorenzo I was in the second team.
"We will see if Pellegrini signs for Manchester City.
"His way to play football is great. Somebody told me he is a great manager so we will wait to see what happens. Hopefully if he comes to City he can just carry on with his football."
