NEW YORK -- Conor McGregor is no longer the only brash Irishman making headlines in mixed martial arts.

Enter James Gallagher.

The unbeaten featherweight, a training partner of McGregor under coach John Kavanaugh, made a massive statement Saturday during a showcase bout on Spike TV, before the start of the Bellator NYC pay-per-view from Madison Square Garden.

The 20-year-old Gallagher needed just two minutes, 22 seconds to take down and submit Chinzo Machida (5-3), the older brother of former UFC champion Lyoto Machida, in a dominant first-round submission win.

Gallagher (7-0) landed a big right hand to open the bout and instantly took Machida down. He quickly took full mount, and then Machida's back, before choking the Brazilian with his right arm and landing big strikes with his left hand, opening a cut over Machida's left eye.

After forcing Machida to tap due to a rear-naked choke, Gallagher jumped on top of the cage, with the flag of Ireland draped across his shoulders. He quickly leaped down and ran into the MSG crowd to celebrate with his family.

His performance caught the eye of his teammate McGregor, the UFC's lightweight champion, who was busy training for his Aug. 26 boxing match against Floyd Mayweather.

Gallagher was brash and cocky from his cage walk through the opening announcements, when he got up into Machida's face and taunted him. After the fight, he continued the theatrics during the post-fight interview.

"When I say I"ll do it, I'll always come and do it," Gallagher said, before referencing Madison Square Garden as his own house. "This is my place!"

Gallagher, who improved to 4-0 with Bellator, didn't hesitate when asked who he wanted to face next.

"I want the f------ belt," he said, before instantly pointing up to a banner hanging from the arena ceiling of featherweight champion Patricio "Pitbull" Freire. "Tell him to bring his belt because I'm taking it."

It didn't take long for Freire (26-4) to respond on social media.

Bellator clearly has a young star and ratings grabber on its hands in Gallagher, who felt at home when compared by media members after the fight to McGregor.

"Getting compared to the GOAT? The man who will knock out Floyd [Mayweather]?" he said. "I'll take that all day."
