Manila, Philippines – May 7, 2025 — Fresh off his stunning victory to claim the world championship, Filipino boxing star John Riel Casimero has delivered a brutal message to his longtime rival Naoya Inoue — and it’s only five words:
“He’d best retire right now.”

Speaking to reporters after his championship win, Casimero didn’t mince words when asked about a possible rematch with Inoue. With a confident smirk, Casimero declared:

“I’ve beaten him. It’s over. He’d best retire right now.”

Casimero’s message is a clear ultimatum aimed at Inoue, who recently suffered a career-shaking defeat at Casimero’s hands after a grueling 10-round war. While Inoue has yet to officially comment on his future, speculation is swirling that the Japanese superstar may be considering stepping away from the sport.

Casimero added:

“There’s no point in him coming back. The king has fallen. I respect what he’s done, but it’s my time now.”

The statement quickly went viral, with fans and analysts weighing in on whether Inoue should seek redemption or take Casimero’s advice and walk away with his legacy intact.

For Casimero, the victory marks a career-defining moment — and his bold words make it clear he’s ready to take center stage as the division’s new king.

As for Inoue, the boxing world now waits to see if he’ll respond with his gloves — or with a retirement announcement.
