Conor McGregor warned fourth fight with rival Dustin Poirier would be "weird"

Conor McGregor has been warned that pursuing a fourth fight with heated rival Dustin Poirier would result in a "weird" event.

UFC legend Chael Sonnen was discussing McGregor's next options when he noted that while there is a story to be told between the pair, it's a tougher sell given McGregor was stopped twice in a row.

McGregor was cleanly knocked out in their rematch last January at UFC 257, before the slightly more controversial UFC 264 ending which saw him cleanly break his leg while stepping back from a kick.

“Poirier vs Conor works," Sonnen said in a YouTube video. "I understand that but part four is a little weird.

Their first meeting was at featherweight in 2014, which McGregor won within minutes, before they reignited their feud last year at lightweight.

McGregor has a history at welterweight in the promotion, while Poirier has flirted with making a move up after losing his two efforts at the undisputed lightweight title.

One thing that Sonnen does know with confidence is that McGregor has the ability to make a fight big regardless of who his opponent is set to be.

“Conor has been for a meaningful period of time and will live the rest of his career on the same unique spot that
