Carl Frampton has set his sights on WBA regular world champion Scott Quigg after his impressive fifth-round stoppage of mandatory challenger Chris Avalos at a raucous Odyssey Arena in Belfast.

The Northern Irishman was making the first defence of the world crown he won by defeating Kiko Martinez last September and he did not disappoint his vocal home fans on Saturday night.

Frampton rocked his American opponent in the second round and then stepped up his assault in the fifth before referee Howard John Foster stopped the contest midway through the round.

Frampton told ITV1 directly after his win: "I would love it. I think Scott wants it, it's a summer showdown between the both of us. It's a massive fight but Scott needs to remember who's the real world champion."

The 28-year-old added he would be happy to fight outside of Belfast in order to guarantee an encounter with fellow unbeaten fighter Quigg, who was ringside to see his rival bolster his standing as one of the best fighters in the division.

"I would leave Belfast if I had to. Maybe somewhere neutral, it doesn't matter to me," he added.

"I think Scott would agree with me. It's the biggest fight in the UK (other than) Amir Khan-Kell Brook possibly, but I think this one's been brewing a lot longer. It's a huge domestic showdown."

Quigg - who holds a secondary version of the WBA title, with Cuban Guillermo Rigondeaux the body's super champion - is just as keen to arrange a bout.

"This fight is big, not because of him not just because of me, it's the full package. The British public want the fight," he said.

"He draws the crowd in Ireland, we draw the crowd in Britain, wherever. It doesn't matter where the fight is, wherever it holds most - get the fight on."

Frampton's win was the perfect birthday present for his manager, mentor and promoter Barry McGuigan, the former WBA featherweight champion.

McGuigan, who turned 54 on Saturday, said of his charge: "This is the best super-bantamweight in the world. There are aficionados out there who think Rigondeaux is.

"He's the best super-bantamweight in the world. That includes Leo Santa Cruz, Scott Quigg and Guillermo Rigondeaux. He's a sensational fighter and over the next couple of years we're going to prove that."
