"I've always said he's a great goalkeeper. I've been here a long time now and he is the best 'keeper I've played with," said the Liverpool vice-captain.
"He's beaten some records at this club already and that's testimony to what a top class goalkeeper he is.
"For me he is in the top three in the world. I think Cech, Buffon and Pepe are the best around and you can put them in any order you want, there's not much difference between them.
"It's great as a defender to have a goalkeeper you can trust and who you know you can rely on. I think if we were nervous about the goalkeeper and worried that any mistake you made would end up as a goal, then it would affect your play."
