Rodgers was pleased with the performances of Jose Enrique and Glen Johnson in the 1-0 win.
He told liverpoolfc.com: "I thought Jose Enrique was unplayable [against Southampton], and Johnson too.
"So you see those two bombing on, you've got your controlling midfielder protecting the centre halves in that defensive triangle, your two advanced midfield players joining in Joe and Steven, and then you've got your front three. That gives you a real creative threat, and I felt we had that today. Today, especially in the first half, was probably the first time it was really there systematically and relentless."
