Canelo Alvarez is pondering a switch to light heavyweight to fight WBC and IBF champion Artur Beterbiev, according to Eddie Hearn.
Before the Mexican makes any decision, he will focus on making super middleweight history against Caleb Plant.
Following Alvarez's May victory over WBO super middleweight titlist Billy Joe Saunders, Plant's IBF belt is the one the 30-year-old needs to become the division's first undisputed champion.
"That's the plan. I'm coming, I'm coming my friend," said Alvarez in the ring after Saunders' corner retired their man after round eight with a fractured eye socket.
Alvarez's business associate Hearn says he will now press ahead with trying to make a September fight between the four-division king and Nashville's Plant.
Hearn told Little Giant Boxing: "We're going to talk through the next move.
"Of course, we've made it clear we want the Caleb Plant fight and it's time to start getting that into full process now.
"He's probably ready to get back to work now. Ultimately, Saul [Canelo] and Eddy [Reynoso] will tell me what to do…
"Canelo Alvarez is the absolute pound-for-pound king, he has the right to fight whoever he wants.
"But the good news is he's fighting champion after champion after champion. He will fight anyone."
Plant, 28, defended his world super middleweight title in January with a dominant, unanimous points victory over fellow American Caleb Truax.
That took the 6ft 1in Plant's record to 21-0 and he is as equally keen to get matched up with Alvarez after a December clash was called off.
The pair were set to face off in 2020, but time constraints meant promoting the fight was difficult and the fight got scratched.
Instead, Alvarez fought and defeated Callum Smith before stopping Avni Yildirim in February and Saunders last month.
Light heavyweight switch
With the super middleweight unification pencilled in for Mexican Independence weekend, plans are already afoot for Alvarez to step through the weights.
Having already successfully jumped up two divisions from middleweight (160lbs) to light-heavyweight a step back up to 175lbs will not phase him.
He knocked out Sergey Kovalev to win the WBO world title in November 2019 and has set his sights on another Russian fighter.
Beterbiev (16-0) is the only champion in boxing with a 100 per cent KO record and holds the WBC and IBF light heavyweight belts.
"Maybe after this he'll go to light heavyweight and he may fight Artur Beterbiev and he may fight Dmitry Bivol," Hearn added.
"He doesn't care, he doesn't care. He told me about Beterbiev.
"I said, 'Woah, shouldn't we fight Bivol first?' [He said], 'No, we want him.'
"That's the beauty of Saul Alvarez, he will fight anyone."
