Terence Crawford's future is unlimited after he became a three-division world champion by winning the WBO welterweight title, according to promoter Bob Arum.

Crawford dominated Jeff Horn in New York on Saturday, earning a ninth-round stoppage to take the belt and insert himself in the conversation for top fights in an extremely intriguing welterweight division.

A champion at lightweight and a unified king at light welterweight, there are a number of enticing options out there for Crawford at 147 pounds. 

IBF title-holder Errol Spence is seen by many as the top welterweight, while Danny Garcia and Shawn Porter will fight for the WBC strap in August and WBA champion Keith Thurman is expected to return from injury in September.

Speaking at the post-fight media conference, Arum said of Crawford: "His future is unlimited. He's a terrific fighter. It's the highest praise I can give a fighter, a welterweight, that he reminds me of Sugar Ray Leonard.

"That to me is a great, great compliment because I always thought Leonard was the best, and this guy is equal or better than Ray."

Crawford stated his intention to unify the division, saying: "We want them all [the belts].

"I feel like I'm getting better and better, feel like I'm stronger, more energised, I feel like this is a great division for me.

"I believe I'd do well with any welterweight in the division.

"I think they're all going to respect me now, I think I just displayed my talent and my power. He's supposed to be a big welterweight in the division and they've seen how I dealt with him. 

"We're going to make up a plan and see where we go, but I assure you that we're looking for the biggest fights out there."
