36-year-old Gareth Barry is confident he can play until his 40 years of age.
"It's definitely a possibility. I was 32 when I signed for Everton and (the manager) Roberto Martinez said, 'You're style of game - you can play until you're 40'," he said.
"I'm sitting there laughing at him, but he was deadly serious, and I still laughed. It's still going to be tough, but for a manager to tell me that four to five years ago is a good compliment, which was nice to hear.
"I'm immensely proud to get there. Whether it will stay around for long I don't know."
