Islam Makhachev was able to see off the challenge of Alexander Volkanovski in the latter's home country as the Russian secured a unanimous decision to retain the lightweight title at UFC 284.

In front of an excitable crowd in Perth, Australia, both men put on a fine show in the main event as they also fought for the title of pound-for-pound best in the world.

Despite the unanimous decision (48-47, 48-47, 49-46), it was an undeniably close fight, with Volkanovski getting some early shots in and denying the champion some takedowns.

After initially showing caution, Makhachev soon came to the party and eventually completed four of nine takedown attempts, and somewhat surprisingly bested his opponent in terms of total and significant strike percentage, though Volkanovski's volume was predictably higher.

"You like or you don't like, I am [the] best fighter in the world right now," Makhachev said after the win, much to the crowd's displeasure.

"I show why I'm No. 1. They have to improve more."

The Australian delighted his many fans in attendance with a late surge, but Makhachev had already done enough, particularly in the fourth round when he spent the vast majority of it on his opponent's back.

"He didn't respect my wrestling, grappling," Volkanovski said. "Maybe I didn't respect his striking enough, either. He landed some shots. Fair play to both of us."

In the co-main event, Yair Rodriguez submitted Josh Emmett in the second round to claim the interim featherweight championship with a dominant performance.

In his first ever UFC win by submission, Rodriguez – who also landed around three times as many total and significant strikes – was able to get Emmett in a triangle choke to tap the American out at four minutes and 19 seconds in round two.
