The UFC returns to Paris this weekend as Ciryl Gane takes on Sergey Spivak in a heavyweight headliner. It will be Gane's first fight since losing to Jon Jones in their heavyweight title fight earlier this year. Spivak, meanwhile, will be looking to make it four wins in a row and earn arguably the biggest victory of his career.

The co-main event is also an interesting fight as women's flyweight contender Manon Fiorot welcomes two-time women's strawweight champion Rose Namajunas to 125 pounds as the division gets new blood. With all that in mind, here are three of the biggest questions leading up to UFC Paris.

1. How will Ciryl Gane respond to Jon Jones setback?

Ciryl Gane is in unfamiliar territory. After starting his MMA career with a 10-0 record, he's now lost two of his last three fights. His last fight against Jones was not a particularly good showing. While there's no shame in losing to arguably the greatest fighter of all time, Gane was extremely underwhelming and was beaten far too easily. It's fair to say his stock dropped tremendously in the process.

However, he bounced back from his first career setback against Francis Ngannou with an impressive knockout victory over Tai Tuivasa last year. That fight happened to be in the UFC's debut event in Paris as well. Can “Bon Gamin” do the same against a tougher opponent in Spivak? He certainly believes he can while sending a message to the rest of the heavyweight division in the process.

“The better way for me is to do exactly what we did the last years – to put a big message this Saturday, and the message is: ‘I’m still here, I want to go back to the belt.’ This is the better way, shorter way to go to the belt.”

2. Will Spivak take the fight to the ground?

It can't be avoided, though — both of Gane's losses have largely come on the ground. While Gane has shown some wrestling and grappling on the ground early in his UFC career, those were against low-level fighters. Against the very best, he seems to struggle, though one could argue a severely compromised Ngannou wasn't that much of a ground threat and Gane still struggled against him on his way to his first career defeat.

Spivak likes to strike and get knockouts, but he's more than adept on the ground as he seems to have a sambo background and has submission wins notably against Tai Tuivasa and Derrick Lewis. He also likes to fight in the clinch which could offer plenty of opportunities to get trips in on Gane. While Spivak will be confident that he can finish anyone on the feet, he may be better served by getting the fight to the ground and potentially ending it with ground and pound or a submission.

3. Is Rose Namajunas taking a big risk?

Rose Namajunas is moving up to flyweight for the first time and overall, just needed a change of scene. With Weili Zhang now the women's strawweight champion, Namajunas — who holds two wins over her — could have easily challenged her for the title. But that didn't give her the motivation she was looking for compared to moving up and fighting bigger opponents.

“Weili’s the champ now, so what, I fight her a third time? I don’t know, it’s just not every interesting,” Namajunas said during media day. “I’ve already fought [Jessica] Andrade and this and that and now she’s gone back down… Weili’s the champ, so then I could just beat her again, but I don’t know, to me it’s more than that.

“I want something that scares me. I want to face my fears. It’s just always been a part of the plan and yeah, I could keep doing the same old thing, but as soon as this game gets redundant, I can get bored really quick and that’s not good for nobody. So I need to keep it fresh and interesting.”

Namajunas will certainly get a fresh and interesting opponent in Manon Fiorot who is undefeated in the UFC with a 10-1 record overall. She's coming off wins over Katlyn Chookagian, Jennifer Maia and Mayra Bueno Silva. She is also capable of finishing fights with six knockouts in her 10 professional wins. Not to mention the fact that she'll be a bigger opponent with a two-inch height advantage and being accustomed to fighting at 125 for much longer.

Namajunas mentioned that the weight cut to 115 was getting harder, but she was built well for the strawweight division. It remains to be seen for now how she'll fare against Fiorot on Saturday, but hopefully, she doesn't end up regretting the move.
