Frankie Edgar is more than willing to accept Conor McGregor's invitation to clash in the octagon.
The Irishman named Edgar as one of several opponents he is keen to fight when he returns to the UFC.
McGregor's preference is to fight the winner of lightweight champion Khabib Nurmagomedov's title defence against Dustin Poirier next month.
He said: "I'm not going to wait around, if Dustin does it, it's Dustin, if it's Nate [Diaz], Nate, if it's Jorge [Masvidal], Jorge... Tony Ferguson, Justin [Gaethje], [Max] Holloway, the [Jose] Aldo rematch.
"Frankie Edgar is also up there because he has similarities to Khabib, he runs on the back foot and shoots on the single leg.
"Frankie has been very respectful, he said he wanted to tell his grandkids he fought Conor McGregor one day."
And Edgar took to Twitter to respond: "You know I'm down to fight, it should have happened a long time ago.
"I know I'm going down to bantamweight but for you any weight class will do. Any time, any weight class; you know I'm game."
McGregor has not fought since he lost to Nurmagomedov last October, and hopes to return later this year
"There are so many bouts for me but it doesn't matter, it's about getting back in and being who I am, not a shell of myself, not half-committed," he added.
"I'm already in shape, I haven't lost my condition, I just need to sharpen up the grappling. I would look for that, for the end of the year."
