Rodgers has huge admiration and respect for the defender.
Rodgers told Liverpoolfc.com: "He's a phenomenal character. I've watched him from the outside for many years and to play 700 games at a club as prestigious as this is incredible.
"The pressures that come with wearing the shirt at this club are vast and for him it's a way of life. He's devoted his life to being a football player. He's 34 now, so it doesn't get any easier when you are older, but certainly I've been very impressed over the course of the pre-season.
