Top Rank's CEO Bob Arum is very much on board with making a catch-weight showdown between eight division world champion Manny Pacquiao (59-7-2, 37 KOs) and WBO super featherweight champion Vasyl Lomachenko (10-1, 8 KOs).

Earlier this week, Pacquiao did an interview in the Philippines where he made statements claiming that his team was actively negotiating a potential fight with Lomachenko, at 140-pounds.

But then a day later, Lomachenko's manager Egis Klimas denied that a Pacquiao fight was being discussed and felt their weight disparity was too much at the moment.

The weight is the biggest snag, with Pacquiao currently fighting at 147 pounds and Lomachenko at 130. Klimas also believes that Pacquiao, being 39 years old, brings very little in terms of pushing Lomachenko's career forward - as he feels most experts will not give his boxer credit for beating an "old" Pacquiao.

But Arum says Lomachenko will be making his lightweight debut in the coming months. He was seen in action back in December, when he dominated fellow two-time Olympic gold medal winner Guillermo Rigondeaux for a sixth round TKO at MSG's Theater.

While Pacquiao is also expected to make his ring return in April - fighting for the first time since losing an upset twelve round unanimous decision to Jeff Horn last July at the Suncorp Stadium in Brisbane, Australia.

And then the veteran promoter would love to match both boxers in the fall - but he admits that everything depends on Lomachenko's father and head trainer - giving his approval for his son to face the Filpino star at 140-pounds.

“Lomachenko will be having a fight that will probably be at 135 at the end of April,” Arum said to the Las Vegas Review Journal.

“Lomachenko’s father (Anatoly) would then need to give him permission to fight Manny at 140 pounds in the fall, and that’s a fight we’ll hopefully might want to put in Las Vegas if a building is available.”
