“There’s only one… Conor McGregor!” as the song goes.

Irish fans of “The Notorious One” sing it loud, and often, whenever the fighter appears.

Of course, that’s just one of many variations of the same song which British and Irish sports fans sing, to the tune of  old carol “Winter Wonderland.”

The fans of boxer Ricky Hatton used to sing the same thing, but with Hatton’s name at the end of the line.

There’s only one… Ricky Hatton

There’s only one… Ricky Hatton

A beautiful sight, we’re happy tonight

Walking with the Ricky Hatton man…

Across the pond, California MMA and boxing coach Edmond Tarvedyan took the idea one step further.

Tarvedyan is best known as the trainer of UFC Women’s Bantamweight Champion Ronda Rousey, who was recently announced to next fight Bethe Corriea at UFC 190 in August.

Rousey is so unique, says Tarvedyan, that it would take five Bethe Correia’s to challenge here — and they would fail too.

“There could be five of her,” Tarvedyan says of the challenger. “Five chicks like that, they can’t do s— to Ronda.”

Asked how he imagines the fight will look, Tarvedyan says its all a matter of when, and how, she wants to win.

“I think Ronda wants to beat her up a little bit because of the way she’s been talking,” Tarvedyan boasted. “That was the plan with Miesha Tate because these two, they like to talk a little bit, you know; and Ronda beat up Meisha Tate pretty bad before she submitted her. [She] rocked her into the third round. She didn’t know where she was.”

Tarvedyan even boasted that Rousey could beat Leila Ali or Holly Holm in boxing matches, and that she would “demolish” Invicta Featherweight Champion Cris “Cyborg” Justino should the two ever fight.
