Roberto Martinez insists age is not a barrier for the evergreen Sylvain Distin.
The French defender, who turns 36 next week, has been linked in media reports with a new contract at Goodison.
The Blues chief says that the ongoing quality of Distin’s football will decide his future.
Martinez told evertontv: "When you get in a situation like Sylvain's, it's not the manager making decisions, it's football.
"I'm proud to have a player like Sylvain Distin representing Everton because he has got incredible standards.
"All we need to do is carry on doing the same thing and then at the end of the season football gives you the reward that you put in as a professional."
Distin's Everton teammates often credit the centre-half's professionalism as one of the fundamental reasons behind his extended career at the top level.
Martinez endorses this suggestion and even believes that the former Newcastle United and Manchester City man is playing the best football of his career.
He added: "Sylvain has been an incredible performer this season. I wouldn't say he has just carried on where he left off last season, he has stepped up and has gone to a different level.
"He has always been paramount in our defensive duties but now he is very important in our style of play and the distribution that he brings to the team.
"Age becomes a number. Sylvain looks after himself - he is always the last man out at Finch Farm and he could play for a long, long time.
"The number becomes experience in football and it can be used to your advantage. We need to enjoy this player who is a true ambassador of our football club."
