Everton boss Roberto Martinez says Leon Osman can extend his stay beyond his new one-year deal.
The Toffees announced on Thursday that Osman had agreed a one-year extension to his current contract, taking him through to the summer of 2016.
Speaking ahead of Sunday's Barclays Premier League trip to Sunderland, Martinez said of Osman: "You don't get many footballers like Leon.
"You don't get so many players celebrating testimonials in the modern game.
"And then you look at the way he is enjoying his football, the way he is efficient and effective in games, and the way he took his goal on Thursday - I think that is him, if you want to have a snapshot of what he brings in a game.
"He has great composure, arrives into the box and shows real style and quality to score the goal.
"The extra year is a reward he deserves, and now he is not waiting until the end of the season.
"But signing the reward of a year's deal doesn't mean you are going to retire at the end of that contract.
"The club is moving forward and we have a policy that any player over 30 has to prove their fitness so that we are up to speed year by year.
"And I hope Leon Osman is fully fit for many, many years to come and can write many other pages of history with Everton.
"He is very close to 400 appearances, and is a special figure for us."
