UFC 269's co-main event had one of the most shocking upsets in the promotion's history. Julianna Pena beat Amanda Nunes to become the UFC bantamweight champion. Many had it as the biggest upset in UFC history, except Michael Bisping.

Michael Bisping knows a thing or two about upsets in UFC title fights as he holds a big one himself. His knockout win over Luke Rockhold at UFC 199 is one of the biggest title fight upsets in history.

The former middleweight champion gave his thoughts on the upset at UFC 269. He doesn't see it as the biggest upset ever.

“In terms of the Peña-Nunes upset – which it was an upset, it was a huge upset, a lot of people said it’s one of the biggest upsets of all time that we’ve ever seen in the UFC. I disagree,” Bisping said on his YouTube channel via MMAFighting. “I think Julianna Peña should be extremely proud of herself. Of course, she just became a champion, she just realized a dream. She defeated the female GOAT. An incredible achievement, BUT it’s not the biggest upset.

“Matt Serra beating Georges St-Pierre, I think it tops (Peña-Nunes). I think according to the bookies it was the biggest upset of all time and then when you consider the fact that Matt Serra wasn’t even a current UFC fighter. Matt Serra at the time had been released from the UFC, came back, won the ultimate fighter, that’s how he got a shot at the belt, and I don’t think anyone gave him a hope in hell of beating Georges St-Pierre and he went out there and absolutely demolished him. So that’s my No. 1.”

Many agree that GSP-Serra is one of, if not, the biggest upset in UFC history. Many consider Holly Holm vs Ronda Rousey to be up there as well.

Michael Bisping expects things to go much differently in a rematch. He sees Amanda Nunes getting the job done the second time around.

“I think she’ll come back and I think she’ll fight Julianna Peña and I think she beats Julianna in a rematch,” Bisping said. “In that first round, she outclassed Julianna. She was the better person, she put her down twice, she controlled her in the clinch, she controlled her on the ground. It was a good round for Nunes but she got tired. She got tired, you could clearly see it. And also she showed a little naivety, she showed a little lack of experience, she showed a little – she didn’t show the best fight I.Q.

“When you’re in a fight – and I’ve been there many times – when you’re in a fight, you’re in the UFC, you go in there and it’s a big fight, a main event or whatever, there’s thousands of people and you’re the f*cking star and things don’t go your way and BANG you get caught with a shot and you’re rocked, what we saw Nunes do – and it’s commendable and the crowd loved it and they’re all screaming and cheering – she just stood there swinging back and forth…. What Nunes should have done was be a little bit more crafty. She should have got on her bike, use her footwork to be a little bit more elusive, dance around the octagon a little bit, get your equilibrium back…

“Nunes probably beats her in the rematch. I’m not taking away from what she did. I honestly believe Nunes will beat her in the rematch.”

Some have hypothesized that Amanda Nunes could retire after the loss as it was rumored that the UFC champion was thinking of stepping away. Michael Bisping isn't sure about any of that as he thinks she still has more to prove.

“I think Amanda Nunes will 100 percent go in there and fight Julianna Peña a second time,” Bisping said. “You can’t deny her heart, you can’t deny the body of work that Amanda Nunes has had, the skill that she’s got. You can’t deny any of that. She made some mistakes Saturday night. She got caught up in the moment, she wanted to fight fire with fire, she ran out of steam, she got gassed. You can blame it on Covid, you can blame it on whatever you want, but she got beat. Julianna Peña was the better person on the night. Nunes is gonna want to get that back, she’s gonna want to get that belt back and get her respect back, so make no mistake, I think that’s what we see next.”

UFC 269 is going to prove to be an important moment in Amanda Nunes' career. The former champion is going to want to come back and prove her status as one of the greatest of all time.
