Rodgers knows he has two great role-models his young players can look up to.
He said: "Whenever I see Jamie Carragher on his knees at the death of a game like on Wednesday, aged 34, whatever he is like physically, that is his commitment mentally.
"It is about the hunger and desire and that is why you admire big players who stay at the top for as long as they can because it is not just what they are doing in games.
"In order to be like that that is what they are doing every single day of their life.
"Christ, you see these guys in at the right time, eating the right food, their weight, their body fat are immaculate.
"It is a way of life and if you prepare yourself right and are prepared to work hard that gives you confidence and then confidence will ultimately lead to success."
