“Hopefully [my best years are still ahead of me]. People say goalkeepers reach their best in their 30s, and I am 30 right now, so hopefully my golden days are still waiting for me.”
Reina also insisted his team-mates deserve a great deal of credit for Liverpool's recent impressive defensive record.
He added: “It's down to the defensive performance, collectively. We are all together in that in making those improvements.
“I've always said a good team is built from the back and this is no different. There's no doubt that the more clean sheets we keep, the better it'll be for the team.”
