"To play 200 games for Liverpool is a massive figure," said Benitez.
"I am really pleased for him and hopefully he can play 200 more which will be very good for us.
"Pepe is a fantastic worker and his mentality on and off the pitch is really good. He is always training very hard and trying to improve every day. He is a very good professional.
"The goalkeeper, especially in a top side, is important because normally you are attacking and he will be involved in the game just one or two times.
"If he can make a great save and keep you in the game that is massive for the rest of the season."
