The Reds head to Blue Square Bet Premier outfit Mansfield tomorrow on the back of two successive Barclays Premier League wins.
However, they have won three games in a row only once since October 2011 and that was last month when victories over Southampton and West Ham sandwiched a tight Europa League success over Udinese.
And while Rodgers is set to rest key players like Luis Suarez and Steven Gerrard he remains confident they have enough to get through the third-round tie - something Liverpool have failed to do in three of the last six years.
"Our preparation is exactly the same as if we were playing Manchester United and our focus is to go there and win," he said.
"You know these games can be tricky but if you do your job right and you compete then your quality should come through. It is up to us to get the job done and move on.
"Some of the players have played a lot in the league, so it's an opportunity for them to recuperate. But I would never put the tie at risk because it's a tournament we want to do well in.
"Sometimes these early rounds can be the most difficult. I'll do what I've always done - pick a team to win. It's about being professional and doing our job. If we do that, we'll be fine.
"You've got to make sure you get your approach right. If you do that, you hope your qualities come through."
