Pellegrini predicted that Liverpool, who finished second to Premier League champions City last season, will be one of the clubs challenging his side for the title this season.
Pellegrini said: "The pre-season is different than when you are playing for the Premier League.
"Tomorrow is important for us to win, but during the year I think that not only will Liverpool be our major rival but also Chelsea, Manchester United, Arsenal and Tottenham. There are a lot of very strong teams that can win the Premier League."
The City manager was speaking at a press conference ahead of City's International Champions Cup clash with Liverpool in New York on Wednesday.
