WBO welterweight champion Terence Crawford would like to get in the ring for a unification with WBC, IBF champion Errol Spence or WBA champion Manny Pacquiao, according to Top Rank President Todd DuBoef.

And another option is former welterweight champion Kell Brook, who is pushing to face Crawford.

"Yes, absolutely [Brook is an option]. Brook has made some overtures and had dialogue about the fight and Crawford is interested. We have been open to fighting everybody with Crawford since the minute we signed him. Brook is obviously an option," DuBoef said to Sky Sports.

"Crawford wants to fight Errol Spence Jr or Manny Pacquiao badly but Brook is a possibility. So are Josh Taylor and Jose Ramirez. We are open to everybody."

Crawford has been out of the ring since December, when he stopped Egis Kavaliauskas. During his career, Crawford defeated two British stars in Ricky Burns and Amir Khan.

Brook recently revealed that he personally spoke with Crawford and Top Rank CEO Bob Arum - and both had expressed interest in making a fight this year.

The Sheffield fighter has been competing in recent years at junior middleweight, but claims there will be zero problems when it comes to getting down in weight to the welterweight limit of 147-pounds.

"I saw Bob Arum out in America, I saw him walking through the lobby in the MGM Grand. I basically went over and said: 'You're running out of opponents for Crawford and I'm the guy to beat him. I'm here,'" Brook said.

"I saw Terence Crawford, he said he was ready for it, so everybody is on the same page. Everyone wants to make the fight. We just need to make the numbers count for me, for it to make business sense, and then we can get training and get ready for the fight."
