The Latics won 2-1 at Anfield last season in what proved to be a huge result in their retaining of top-flight status.
Rodgers said: "I've got a lot of respect for Roberto [Martinez]. I knew he had done a terrific job at Swansea and the impact he made there.
"He went to Wigan, another club he knew very well, and has done an excellent job there. Our philosophies are on the same line in terms of how we want to work and he's done a terrific job, none more so than last season because Wigan beat Liverpool at Anfield.
"So I know it's going to be a tough game and as I said he's a good guy, a good man, who works hard. He's a guy who has been at the top of the game for a few years in this country and he's done a terrific job at Wigan."
