"Back in September, Pepe Reina had a difficult afternoon at Birmingham and I said at the time that we need to see how he reacts to that and adapts to English football," said the former Liverpool captain.
"He's done so exceptionally well. He's worked out when to come for crosses and when to stay on his line. Basically, he's worked out what the right thing to do is. No one should ever underestimate how important having a good goalkeeper is to a team, and Rafa Benitez has signed a really good one.
"He said at the time that Reina was a great goalkeeper and that has been proved right. On Sunday we saw a good player in Stelios go clean through and although he didn't hit his shot too well, Reina made a world-class save. Anyone will tell you what a world-class goalkeeper is there for, and the big teams have all got them. Liverpool have been missing that, but that's no longer the case."
