City came from a goal down for the fourth competitive match in a row, as they held the Reds to a 2-2 draw at Anfield.
"It was difficult to adapt to the new system but I think the lads did well," said Rodwell on City's official website. "In the first 30 minutes we dominated the game and we got back into it in the second half, so we have to take the positives from that.
"It showed great character to come back from being behind twice and Carlos [Tevez] scored a great goal.
"We have to keep grinding these points out away from home, especially at places like Anfield and we'll just take away the positives from today."
City's next Premier League game is against Queens Park Rangers at the Etihad Stadium on Saturday.
