Everton skipper Phil Neville feels he has another three years at the top.
Neville has flown out to an Austrian training camp with the rest of the squad who have so far returned for pre-season training but he has been putting in a bit of extra work to ensure he can keep up with the younger players in the side.
"I worked quite hard over the summer. I went on holiday but I trained at a facility for a couple for weeks - that is par for the course now," he said.
"Particularly when you are getting older you have to stay ahead of the game. At the clinics I went to over the summer to do my training I learned that age is just a number.
"I want to play football for as long as I possibly can: two, three more years hopefully at the top level. The way that science is improving now players can play for as long as they possibly can."
