McGregor answered questions from fans earlier this week on Twitter and made it clear he would 'spark' Usman if they ever clashed.
The former featherweight and lightweight champion said: "Tremendous! I love this record! I fight for the 170lb title I will spark him too. That would be fastest KO in a UFC title fight (13 seconds).
"Most knockdowns in UFC title fight (five) And then another KO in a UFC title fight. 3 title fights. 3 KO's. 3 new records. It's right there!"

However, it didn't take the 'Nigerian Nightmare' long to send his own chilling warning to McGregor.
Usman stated: "Spark who?? You must be talking about that pipe you've been smoking. Unlike you, if I'm gonna talk s**t I'll @ U. Now be quiet before I call Poirier or Khabib or Diaz to finish you again. #P4P."

McGregor and Usman have been involved in public war of words in the past but a fight is yet to materialise.
'The Notorious' is currently out with a broken leg he sustained in a loss to Dustin Poirier at UFC 264 in July.
He's on the mend after undergoing surgery and claims to be 'improving rapidly' ahead of his Octagon comeback in 2022.
Asked when he will fight again, he replied: "2022. I'm improving rapidly! Working with the best team money can buy! I'll be back in no time, lock loaded!"
Meanwhile, Usman is set to headline UFC 268 in November against longtime rival Colby Covington.
The event is currently rumoured to be taking place at New York's Madison Square Garden.
