Well, Max Holloway tells TMZ Sports it very well could be him ... 'cause he's on a "short list" to fight The Notorious.

We talked to Holloway -- the 29-year-old, #1 ranked featherweight contender -- just days before he's set to battle #3 ranked Yair Rodriguez ... in what in all likelihood will be a ridiculously awesome fight.

Question is, Blessed technically (it was controversial) lost to Alex Volkanovski twice ... so a win might not necessarily set him up for another crack at the current champ.

So, what's next? Here's what Max told us.

"I got 5 titles wins. 5 title fight wins. I want that 6 title fight win. And, if it can be Alex, then so be it. But, at the end of the day, UFC discussed with us a bunch of things, a bunch of possibilities. I got a win over the 155 champ in their division."

Then Holloway dropped this bit of news sure to get MMA fans juiced.

"I'm on a short list for Conor McGregor. Always on a short list for that fight. I'm the best boxer in the UFC."

Of course, it wouldn't be the first time the men have shared the cage. Back in August 2013, Holloway -- only 21-years-old at the time -- lost a unanimous decision to McGregor.

Fast forward ... Max is considered by most the greatest 145 lb. MMA fighter of all-time, and is coming off a historically dominating win over Calvin Kattar.

Meanwhile, 33-year-old Conor has lost 3 of his last 4 fights (Khabib L, "Cowboy" Cerrone W, Poirier L, Poirier L), and suffered a devastating leg injury against Dustin on July 10.

McGregor is likely to return to the cage in 2022 ... and Max, who's super focused on Rodriguez, knows it'll be huuuge fight.

"I think Conor, he's always talking about Nate [Diaz], always talking about Dustin [Poirier] now. But if you go call Hunter [Campbell] at the UFC, one of the guys here, and ask him who is the guy gonna sell pay-per-views at 45 or 55," Max said.

Holloway even has a venue in mind for the superfight.
