Canelo Alvarez sincerely regrets not inserting a rematch clause in the contract for his fight with Terence Crawford.The Mexican superstar had a huge super-fight with fellow pound-for-pound rated Crawford who stepped up to 168lbs last September.Canelo regrets not mandating a second meeting with Crawford, after being outclassed during their clashGettyAnd unfortunately for Alvarez he was comprehensively beaten in a punch-perfect masterclass from Crawford to snatch his undisputed titles.Immediately, many suggested that a rematch would be the natural option with the former champion spurred on by revenge.But it never came, with Crawford instead opting to vacate the titles and retire from the sport, leaving with an unblemished record.For Alvarez, he thinks it was his biggest mistake, but still believes Crawford should return for a rematch.He explained: “No, it was [a rematch] never discussed.“It was some mistake on my side to not sign for a rematch, because the champion always needs to [insert] a rematch clause and I didn’t, for some reason, but I think that things happen for a reason. “I hope that the rematch can happen, if not, it’s fine – we need to move forward, right?“I’m surprised [he retired without the rematch]. As a fighter, you want a rematch to show it again, and I’ve always done well in my rematches, so it surprised me a lot.“It it what it is. It is his life, his career, and I can do nothing with that. I got the feeling that he’s going to come and fight again, but you need to respect that. If he’s out, he’s out, right? But I hope not.”A second meeting would likely be another mega-money deal after the original event was a commercial blockbuster.Crawford retired after capturing the belts, and has shown no new interest in returningGettyBut it appears further away than ever with Crawford content with life outside of the squared circle.Alvarez is instead focusing on earning his titles back the hard way, with his October 31 clash with WBC champion Christian Mbilli in the distance.Crawford would have accepted rematch, now not interestedAs for Crawford, he is now happily retired and after an opportunity to face Janibek Alimkhanuly at 160lbs collapsed, he was satisfied with his decision.But despite no longer holding interest in a rematch with Alvarez, the 38-year-old insists he would have honoured the clause.He said: “Canelo [rematch] was off the table. “There was no rematch clause. If the rematch clause was in the contract then I would have honoured that.”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.
