Despite sharing a history filled with conflict and disdain, Conor McGregor had only positive words for Jose Aldo following the Brazilian’s big win at UFC on FOX 30.

McGregor (21-3 MMA, 9-1 UFC) and Aldo (27-4 MMA, 9-3 UFC) spent more than a year locked in a deep-seated feud leading up to their encounter at UFC 194 in December 2015. The result of their bout was one of the most memorable in MMA history, with “The Notorious” scoring an iconic 13-second knockout to unify the UFC featherweight title.

Since that fight, Aldo’s fallen on some tough times. He rebounded from the highlight-reel loss with a win over Frankie Edgar at UFC 200, but then suffered back-to-back losses to current 145-pound king Max Holloway and absorbed 278 significant strikes in the two contests.

More than two years removed from his last win, Aldo finally got back on track this past weekend at UFC on FOX 30 when he scored a first-round TKO of Jeremy Stephens. His post-fight celebration was filled with emotion, and in a recent run-in with TMZ, McGregor said he was “happy” to see his old rival achieve a great victory.

“I was so happy for him,” McGregor said. “Honestly, truly happy to see the joy he had after it. It’s a crazy business, and I know he’s gone through a lot of stuff. So to see him come back with that great finish, I was very happy for him and his coach, Andre Pederneiras. The whole of Ireland was happy for Jose Aldo that night.”

Ever since Aldo’s more than 10-year unbeaten run came to a screeching halt courtesy of one McGregor left hand, “Scarface” has expressed interest in a rematch to prove the result wasn’t indicative of the superior fighter. The chances of that happening seem slim at best, though, especially with Aldo hinting that retirement could come once he completes the final three fights on his UFC contract.

Then, of course, there’s McGregor, who hasn’t fought in MMA since he claimed UFC lightweight gold with a second-round knockout of Eddie Alvarez at UFC 205 in November 2015. “The Notorious” is seemingly on the comeback trail, though. In the same interview with TMZ, the Irishman confirmed there are ongoing talks for a title bout with Khabib Nurmagomedov (26-0 MMA, 10-0 UFC) – possibly at UFC 229 on Oct. 6 in Las Vegas.
