#2. Arnold Allen vs. Max Holloway - UFC featherweight division
Arnold Allen may not be the biggest name in MMA, but his 11-fight winning streak has pushed him into the title conversation. He will likely need one more win over a highly-ranked contender to secure a title shot, and there are few bigger names in the sport than Max Holloway.

The fight could make sense for the former UFC featherweight champion if he chooses to remain in the division. It seems incredibly unlikely that he will fight for the title any time soon given his three losses to champion Alexander Volkanovski, so he will have to try and squash the contenders in the division if he remains at 145 pounds.
This fight would be a huge deal in London, as it would bring one of the biggest fighters in the sport to town versus a hometown favorite. Even if Allen were to lose, he would become a much bigger name in a division that needs some new blood.
#1. Leon Edwards vs. Jorge Masvidal - UFC welterweight division
Leon Edwards has already stated his intention to defeat Kamaru Usman and take the belt back to the O2 for his revenge on Jorge Masvidal. The pair had a run in backstage all the way back in 2019, and the bad blood has lingered ever since. After Edwards' title fight, a bout with Masvidal would be very special.
What works in this bout's favor is that it could be booked regardless of whether Edwards wins or loses his bout against Usman. Even with a loss, Edwards would likely land in a similar spot to Masvidal in the rankings, and the demand for this fight would likely not take too much of a hit.
This is the biggest possible fight the UFC could realistically put on for the UK market right now. It could also be a great way to build Edwards as a star, as he hasn’t connected with the fans in the same way as some of the other UK fighters to emerge over the past few years.
