According to eight division world champion Manny Pacquiao, his camp is discussing the possibility of a catch-weight bout with WBO super featherweight champion Vasyl Lomachenko, who is widely considered as one of the best "pound-for-pound" fighters on the planet.

Pacquiao, 39, is looking to return to the ring in April during a break from his duties as a Philippines senator.

His promoter, Bob Arum of Top Rank, revealed on Tuesday to the Las Vegas Review Journal that he's looking to stage Pacquiao's return on April 21, as part of the same card which is going to feature Terence Crawford challenging Jeff Horn for the WBO welterweight title.

The plan for Pacquiao, unless things have changed, is to fight the Crawford vs. Horn winner in the fall.

Even if Pacquiao is negotiating for a fight with Lomachenko, that contest will not happen on the same card as Crawford-Horn - especially for budgetary reasons.

Pacquiao says they are trying to work out the catch-weight.

"There are negotiations now about the number one pound-for-pound (boxer) which is Lomachenko," Pacquiao said in an interview on ABS-CBN television.

"There are still talks on the weight, reducing the weight," said Pacquiao, who has been fighting as a welterweight.

Lomachenko (11-1, 8 KOs), 29, is looking to move up to 135-pounds this year - but that is still quite a weight gap to Pacquiao, who is fighting at 147.

The idea of Pacquiao vs. Lomachenko fight has been mentioned - but there were issues with weight from the start. Lomachenko's handlers had no intention of taking the fight above 135-pounds, and Pacquiao's trainer, Freddie Roach, will not allow his boxer to go under 140-pounds.

Pacquiao, whose loss of his WBO welterweight title to Australia's Jeff Horn last year left his record standing at 59 wins, 7 losses and two draws, is now in the twilight of his career.

The Filipino southpaw retired briefly in 2016 but made a comeback to retake his WBO title from Jessie Vargas just months later. He has not scored a knockout win in the past 8 years.

Lomachenko, who won gold in the 2008 and 2012 Olympics, rocketed to the top of his weight class after turning pro in 2013, winning nine world championship fights in his first 11 contests.

Pacquiao has not climbed in the ring since the Horn loss.

On Wednesday, Pacquiao rejected calls for him to retire for good, adding he did not believe his recent losses tarnished his record.

"You know, I miss boxing," Pacquiao said, adding he was "still okay."
