Claudio Castagnoli is set to return to Arena Mexico this weekend to defend his CMLL World Heavyweight Championship. The Swiss wrestler from AEW will face Ultimo Guerrero on Friday in Mexico City, putting his title on the line in a highly anticipated matchup.
Challenge Accepted: Castagnoli Responds to Ultimo Guerrero
The bout was confirmed after Ultimo Guerrero issued a challenge on Saturday night, which Castagnoli eagerly accepted via social media. This confrontation promises an intense contest for the prestigious championship, adding excitement to the CMLL event at Arena Mexico.
Ultimo Guerrero, I’m so glad you asked,
he said.
Of course, I accept your challenge. I’ll see you next Friday.

Castagnoli’s Championship Journey and Previous Encounters
Castagnoli won the CMLL World Heavyweight title last November by ending Gran Guerrero’s reign. Since then, he has made three appearances in Mexico, including a recent victory in February in a triple threat match against Akuma and Euforia. Notably, Castagnoli defeated Ultimo Guerrero in December in under 12 minutes, marking a previous title defense success. This upcoming match will test his ability to maintain that momentum against a familiar and formidable opponent.
Significance of the Upcoming Defense
This title defense at Arena Mexico carries considerable weight for both competitors. For Castagnoli, successfully defending the heavyweight championship will reinforce his status as a dominant force in Lucha Libre CMLL. For Ultimo Guerrero, this match is an opportunity to reclaim the championship and shift the title landscape. The outcome will likely impact the future storylines and rivalries within CMLL, drawing attention from wrestling fans worldwide.
