Rangers boss Mark Warburton feels that veteran striker Kenny Miller could play on until he is 38 years old, so fit does he look.
The Ibrox giants handed Miller a one-year contract extension earlier this week, something which will keep him at the club until the summer of 2017.
But Warburton sees the 35-year-old, who is set to turn 36 in December, going beyond that and feels he could play on for another three years.
The Gers boss explained to his club's site: "The quality he shows day-in, day-out is first class, so age is irrelevant. It’s about the application and work ethic, and Kenny shows that every single day.
"He has great game and subject knowledge, and he has played at the highest level. He has good ideas about the game and firm ideas about the game, but he embraces new ideas as well", the Englishman explained.

"Watching him every day in training though, there is another two or three years left in the tank for Kenny Miller."
Warburton admits that whether Miller can play on until the age of 38 or even beyond is a matter for the striker, but vowed that Rangers on their part will do all they can to keep him ticking over.
"That will be down to him, but he looks fit, keeps himself well, and the medical and conditioning boys here at the club look after him well.
"So we have all the right pieces of the pie, he is in very good shape, and hopefully that can continue."
Miller will be hoping to get the vote this Saturday when Rangers make the trip to the Tony Macaroni Arena for their next Scottish Championship game, against Livingston.
The Gers currently lead Hibernian by two points at the top of the Scottish Championship and will not want to be overhauled by Alan Stubbs' men at the weekend.
