The Reds have operated with just one central striker for most of the season so far. However, following the completion of Suarez's 10-match ban for biting Branislav Ivanovic, Rodgers switched formation to incorporate two forwards in Wednesday's 1-0 defeat at Manchester United.
He kept faith in that system on Sunday and was rewarded as Suarez and Sturridge contributed all three of Liverpool's goals during a 3-1 win at Sunderland.
Speaking about Suarez after the game, Rodgers told BBC Sport: "He's getting the reward for his hard work in the period he was off.
"He and Daniel Sturridge are a great partnership, they complement each other. We've changed our system a bit to a 3-4-1-2 and it's working well."
Liverpool are currently second in the Premier League table, having taken 13 points from their opening six games.
