City have yet to win away from home this season after they threw away the lead twice to lose to Aston Villa on Saturday.
The defeat at Villa Park comes on the back of a loss to Cardiff and a draw at Stoke City raising question marks over City's form away from the Etihad Stadium.
Pellegrini is refusing to panic about City's results on the road and is optimistic they will turn things around and be in contention for the title come the end of the season.
"I think the Premier League is very regular," said Pellegrini. "I don't know how many teams will be fighting for the title because we are just starting.
"It is a very tough league and the differences between teams are not too much.
"We are just starting working and we hope that we will improve in the future so we can win the games we must win.
"We are not thinking about the title at this moment. We are thinking about winning the most amount of matches. In the Premier League the differences can be very small.
"So we can't know what will happen in the month of May but, playing the way we are playing, I am absolutely sure that we are going to be fighting for the league."
