Gerrard played his 600th game for the Reds on Sunday.
Reina told liverpoolfc.com: "He is always leading by example. He always sets the tempo in training and off the field he is an important figure to follow.
"He knows the club more than anybody and knows the city as well, so he is always there to help you out.
"He is giving his best every day, not just on the training pitch but also in the gym and doing things to prevent injuries as much as he can. Hopefully he will be with us for much longer."
Reina added: "He will be remembered as a legend. A Liverpool legend - and one of the most important players in English history."
