Top Rank promoter Bob Arum is ready to sit down and make a fight happen between his fighter Terence Crawford and Errol Spence Jr.

Crawford (33-0) continued his undefeated run as he successfully defended his World Boxing Organization welterweight title against Jose Benavidez over the weekend by way of 12th round knockout in his hometown of Omaha, Nebraska.

It made boxing fans want to see a title unification fight between him and Spence (24-0) even more, with the latter currently holding the International Boxing Federation welterweight title.

While Spence will likely take on World Boxing Council welterweight champion Shawn Porter in a title unification fight first, Arum is prepared to see him face off against "Bud" in the future, especially as he regards the 28-year-old as the one person in the same league as Crawford.

“All the other guys I discard,” Arum said, as per Boxing Scene. “They’re not in the same league [as Crawford]. Spence may be in the same league. I would love to make the Spence fight."

As is the case in boxing, however, there will be obstacles. This is mainly because Top Rank is with ESPN while Spence is with Al Haymon's Premier Boxing Champions on Showtime.

But despite that, Arum is ready to sit down and make a deal happen, particularly one where no party has the financial advantage.

"You hear me now — I’m ready to make that fight next," Arum added. "I’m ready to make it on very fair terms, where no fighter or no network has an advantage, to do that fight. We’re prepared to sit down and get that fight done. But I can’t force the other people into doing it. You understand?”

Crawford is certainly open to a fight with Spence.

The two recently went back-and-forth on social media last month after Porter defeated Danny Garcia and the pound-for-pound great reiterated his desire once again.

“Al Haymon and Bob could sit down and talk to each other about it,” Crawford explained. “That’s it. I want all them [welterweight champions]. I’ve been saying it. How bad do you want me to say something over and over and over. I said what I said and that’s it.”

While a fight between the two welterweight champions isn't a mainstream draw as of now compared to Canelo Alvarez vs. Gennady Golovkin, technically, it is probably the best fight that can be made today.

This was echoed by former five-weight champion Floyd Mayweather who earlier this year, claimed a contest between the duo could be the biggest fight in boxing.

"Honestly speaking, I think soon the biggest fight that's going to be in boxing is Terence Crawford and Errol Spence," Mayweather said. "That's going to be a huge fight I think in boxing. ... In the future [it's going to be pay-per-view worthy], in the future [it will be pay-per-view] but not right now. I would pay to see it."
