The Chilean says aiming for a draw can be dangerous and has lavished praise on Brendan Rodgers' side for the attacking style they have flaunted in 2013-14
The Reds go into the game four points ahead of their title rivals but having played two games more than the Chilean’s side.
While Pellegrini knows a draw would set his side up to take top spot from Liverpool, he insists City will travel to Merseyside aiming to bring all three points back to the Etihad Stadium.
“Maybe I am wrong, but I always think in the same way as a manager: if you play to draw you will lose,” he told reporters.
“So we are going to play to win. Of course after the game if we couldn’t win the game and we draw it’s a good result, but we are not going to play against Liverpool thinking we must draw. We don’t know how to play in that way.”
Pellegrini also lavished praise on Liverpool and their attacking approach, which has seen them hit 90 Premier League goals in 33 games.
“I am very happy for football. They play attractive football, creative football,” he added
“That’s why I think Liverpool have a lot of merits in the year they are doing so far, because they are an attractive team and they always score.
“Maybe I also am wrong, but I prefer important teams, big teams, than those that just want to win 1-0 and give all the possession of the ball to the other team, score one goal and always defend during 90 minutes.”
