WBA featherweight champion Leo Santa Cruz says he wants a unification fight with IBF champion Lee Selby before facing Carl Frampton again.
Santa Cruz defeated Frampton in a Vegas rematch to reclaim the title he lost in New York last year, but has dampened talk of a third meeting in Belfast.
"I think more likely first I would like to unify with Lee Selby," he said.
"Selby is calling me out, so I want to make it with him and get the win and then fight [Abner] Mares or Frampton."
Selby's camp say they will discuss the prospect with Al Haymon, who advises both fighters, but that a fight with the Mexican would be their "first choice".
The Barry boxer stopped Spain's Antoni Gago on the undercard of the Tony Bellew v David Haye bill at the O2 Arena on Saturday and has made clear he is now a free agent after his four-year agreement with Matchroom concluded.

"We will discuss options with Al Haymon this week," Selby's manager Jamie Sanigar told BBC Radio Wales Sport.
"We want the biggest fights now and a unification with Santa Cruz is top of the list. The winner of Selby v Santa Cruz would be king of the castle in the featherweight division."
Selby is supposed to fight mandatory challenger Jonathan Victor Barros next after their previous fight was cancelled at the last minute.
However, a unification fight with Santa Cruz could well be an attractive proposition to both organisations.
"I want to fight the best. There is Lee Selby, I want to unify against him, Abner Mares, Carl Frampton, I will fight any of them," Santa Cruz confirmed.
"But I think more likely first I would like to unify with Lee Selby, I don't know about a date yet, but maybe June, July, or August.
"We will talk about it."
