Diego Sanchez has reiterated his commitment to becoming the greatest men’s fighter in the history of the UFC.

The 37-year-old has been in the UFC since 2005 during which he has won The Ultimate Fighter 1 at middleweight, going from there to defeat stars like Kenny Florian, Joe Riggs, Clay Guida, and Nick Diaz.

However, the veteran is not settling for less as he says he is gunning at the sport to become the greatest of all time. As he is scheduled to take on Michael Chiesa at UFC 239 her, Sanchez who rides on two winning streak is not worried about his age.

“I’m still here,” Sanchez said during a UFC 239 media scrum (as transcribed by MMA News). “They couldn’t kick me off the shelf. They couldn’t get me off. I’m that dusty book. There’s some experience in that book.

“This is kind of like that ‘Cinderella Man’ movie. That Diego Sanchez, he’s coming back. ‘Isn’t he too old? Nah, he’s doing it.’ Randy (Couture) did it at 45. Diego Sanchez could do it at 36, 37, whatever he is.”

Despite his failure to win a single title in the UFC, having failed to take his chances when the opportunity presented itself against BJ Penn at UFC 107, he is eyeing something bigger than that.

“The question that I get asked the most is, how many more you got left in you?” Sanchez said. “I’m going to fight as long as I can. I love to fight, and as long as I can keep beating these 20-year-old men that they keep throwing in there with me, this will be the third in a row.

“I’m here to be the greatest of all time, and that’s what I’m striving for. Always learn, adapt and evolve. That’s what I’ve been doing for the longest time.”
