"Only the true greats in sport set an unreachable benchmark and his 100 international centuries is Tendulkar's equivalent of Sir Donald Bradman's Test average of 99.94.
Vaughan said that the landmark seemed as if it would not be surpassed.
"Tendulkar has played international cricket since 1989. I can't see a modern player lasting that long. A hundred international hundreds. Just take a couple of seconds to think about that. I thought I had a decent career to score 18," Vaughan wrote in his column in 'Daily Telegraph'.
The former English player felt that the iconic batsman would not hang up his boots as he loves the game.
"What does Sachin do now? Go for 110? 150? Or will he quit? I think he will play on. He loves the game so why should he retire? What else is he going to do? He is in a fantastic position. He can play for the love of the game. He doesn't need the money.
"It is like going back to being aged 11. He can be carefree and enjoy his remaining time especially now the 100 hundreds pressure is off his back."
Stating that just being Sachin Tendulkar for a day would exhaust most people, Vaughan said, "Mastering your game, feeding the hunger for runs and keeping your passion for practice and all those hours working on your game away from the middle are the pillars on which their historic careers have been built."
