Conor McGregor insists that talks for a sequel with Floyd Mayweather remain behind the scenes.McGregor will make his return to combat sports this weekend as he steps into the cage with former rival Max Holloway at UFC 329 in Las Vegas.McGregor has suggested talks to Mayweather have never really endedThe big-selling superstar hasn’t fought for five years, and has declined in form ever since stepping into the boxing ring.In what was his biggest commercial bout, the Irishman touched gloves with boxing legend Mayweather, but was eventually stopped.He gave a good account of himself, and has always teased a return to the squared circle after he is finished with his MMA endeavours.Talks have been held over a rematch in the past and an agreement has come close.And now with Mayweather returning to the sport and in financial crisis, a lucrative second bout would make more sense than ever.McGregor, while speaking at a media day, has suggested that chatter remains ongoing between the two camps over a potential clash.“Yeah, for sure [I’m interested in a rematch],” he told TMZ. “There’s conversations ongoing always. That’s the truth. So, I’m open for it.“I’ll do this again with little Floyd.”Any bout is likely to take huge financial backing from organisers or interested parties.The pair’s bout made history as the second highest-selling bout in the 21st centuryAFP or licensorsAnd McGregor is currently tied down to two further fights with the UFC, and has suggested he will continue to step out under Dana White’s banner for the forseeable future.Could Mayweather vs McGregor 2 happen?The pair would likely fall back into an agreement, given the financial lure that would be involved.Mayweather has faced monetary turbulence outside of the ring, having been threatened by the IRS over unpaid taxes.He was recently set for two exhibitions against Mike Tyson and Mike Zambidis, before a professional rematch with Manny Pacquiao.But the bouts have all been put to one side and postponed, with Mayweather in legal battles over contractual details.If he can move away from said trouble, he will be able to enter an agreement with McGregor, if the Irishman fights out the remainder of his career in the UFC.Watch Boxing on DAZN*If you click a link in this boxout, we will earn affiliate revenueSign up to DAZN to access the definitive subscription for boxing fans.Upgrade to DAZN Ultimate from just £24.99/month, guaranteeing access to 185+ fights annually, a minimum of 12 pay-per-views at no extra cost, as well as every Lega Serie A match and other elite football access.Alternatively, DAZN Standard is just £15.99/month, with the caveat you will have to pay for pay-per-view events.Click here to sign up.McGregor wants to chase a title at 170lbs in the cage, but if he gets beaten by Holloway, may see a clash with Mayweather as a cash-out option.
