Top Rank's CEO Bob Arum has no intention of staging a long negotiation for a potential unification between newly crowned WBO lightweight champion Vasyl Lomachenko (11-1, 9 KOs) and WBC beltholder Mikey Garcia (38-0, 30 KOs).

This past Saturday night, Lomachenko moved up to 135-pounds and stopped Jorge Linares in the tenth round to capture the WBO belt at Madison Square Garden in New York City.

Garcia is rumoured to be facing IBF champion Robert Easter Jr. in a unification being targeted for the summer.

Lomachenko could take on Ray Beltran, who holds the WBO belt, in August. Both Loma and Beltran are promoted by Top Rank. A win could set up a potential four-belt unification with Garcia later this year.

However, Arum is concerned about how the negotiations would go because he says Garcia is always asking for a lot of money and always wants a fight to be completed on his terms.

Also taking into account, Garcia sued Top Rank over his promotional contract in 2014 - and the legal battle lasted for two years. And Garcia is also very loyal to Showtime, while Lomachenko is contractually tied to ESPN.

"With a Mikey Garcia [fight], it becomes like the second coming of Mayweather-Pacquiao," the 86-year-old Arum admitted.

"The negotiations will go on - I may be 90-years-old by the time negotiations finish. I'm tired of that. Whoever's the best available, whichever makes the most sense, that’s what we're gonna go after.

"If [Garcia] wants to fight, let him call me and I'll give him a number. If he doesn't like the number - f*** it - I ain't negotiating! It's because of the way he negotiates. If he's loyal to Showtime and they've been good to him, let him be loyal to Showtime - just don't bother me."
