LAS VEGAS – Just how confident is Georges St-Pierre that he’ll return after a nearly four-year hiatus and win a title in a higher weigh class he’s never competed?

He guarantees it.

St-Pierre (25-2 MMA, 19-2 UFC) and middleweight champion Michael Bisping (30-7 MMA, 20-7 UFC) will fight in the UFC 217 headliner on Nov. 4 at Madison Square Garden in New York. Today they came face to face for a press conference at T-Mobile Arena in Las Vegas.

Much like their first press conference when the fight was announced earlier this year before St-Pierre withdrew, the two men traded verbal barbs. It was jab after jab after jab until, perhaps surprisingly, St-Pierre delivered the proverbial knockout punch.

If Bisping wins, he’ll lay claim to defeating both St-Pierre and Anderson Silva, two fighters often in the discussion for greatest of all time. To Bisping, that would solidify his legacy.

“Yeah, the two best fighters of our generation,” Bisping said. “I’ll beat them both. I beat Luke Rockhold (to win the title), and defended by loss to Dan Henderson. I’m one of the greatest MMA fighters there’s ever been.”

The follow-up question to St-Pierre was whether he agreed. He gave credit where credit was due, but there’s a catch.

“Yes, he is,” said St-Pierre. “But he’s going to lose November 4th. This I guarantee you. He’s not going to beat me. Nothing is more sure.

“Water is wet, fire burns, and I’m going to beat Michael Bisping.”

There you have it.
