UFC champ Francis Ngannou ain’t ready to move on from a possible showdown with Jon Jones . that’s the ONLY fight on his mind.

Ngannou was strolling through Beverly Hills this week when we asked about his fighting future … considering the UFC and Jones seem to be miles (and millions of dollars) apart from making a deal.

In fact, Dana White has repeatedly said he’s targeting Derrick Lewis for Ngannou’s next opponent … and hopes that fight will take place in the summer.

But, Ngannou says he’s still got Jones on the brain when we asked who he wants to fight next — “I want Jon Jones … I love that fight.”

In fact, seems Ngannou is still pretty hopeful the two sides can work out a deal — and we’re guessing every MMA fan out there is hoping he’s right!

When we spoke with White a few weeks ago, he told us he’s “absolutely moved on” from trying to make that fight … and said he doesn’t know if Jon will ever fight in the UFC ever again.

“That’s up to Jon,” White said … “He could absolutely fight again at 205 lbs. He said he wouldn’t fight [Stipe Miocic] and now Derrick and Francis are fighting so we’ll see how that fight plays out.”

“There’s nothing wrong with going out on top either — Jon Jones is undefeated, he’s never been beat.”
