UFC welterweight champion Georges St-Pierre and Anderson Silva battled for the title of pound-for-pound best for several years.

When Silva was topped by Chris Weidman earlier this month, UFC light heavyweight champion Jon Jones vaulted past GSP and into that No. 1 spot in the minds of most.

However, St-Pierre believes “The Spider” is still the greatest of all time.

“I still believe Anderson Silva is the best in the world pound-for-pound. It’s a mistake he made. He got beat by Chris Weidman,” said St-Pierre, during the recent UFC World Tour stop in Las Vegas (thanks to MMA Fight Corner for the quotes). “I believe it was a style matchup and he got caught. I believe he’s the best in the world. Even the best can lose sometimes. When I saw that fight, you know, of course Chris Weidman is my friend and training partner, I was cheering for him and I thought he was going to win because the style match-up and he was very well prepared. But it made me realize when I was watching that fight that even the best can lose sometimes.”

GSP will tangle with Johny Hendricks in November at UFC 167, and the loss by Silva proved to be an awakening for the Canadian.

“As much as I feel happy for Chris because it cannot happen to a better man than Chris Weidman, it woke me up to see Anderson falling like this. As much as I feel happy for Chris, I feel sad for Anderson. It can happen to anybody,” he said. “It made me realize that what I got, I’m the world champion now – it can go away in the blink of an eye.”
