The winner of Saul 'Canelo' Alvarez v Amir Khan is mandated to face Gennady Golovkin and the contracts are signed, says Golovkin's promoter Tom Loeffler.

WBA 'Super', IBF and WBC 'interim' world middleweight champion Golovkin (34-0-KO31) defends his IBF strap against mandatory challenger Dominic Wade in California on April 23, while Britain's Khan (31-3-KO19) takes on WBC champion Alvarez (46-1-1-KO32) two weeks later in Las Vegas.

Loeffler revealed that a deal is already in place for the heavy-hitting Kazakh to try to add another belt to his collection but also opened the door to a fight with current WBA holder, Daniel Jacobs (31-1-KO28).

Of the contracts, Loeffler told fighthype.com: "It's not a verbal. Everything is in writing, signed by our side, by the Golden Boy side and the WBC. We have a good relationship with Golden Boy and a lot of respect for Canelo. It was part of allowing the voluntary defence they requested.

"Everything is mandated. The winner of Canelo v Khan has 15 days to commit to fighting Gennady or not. If they commit then we'll start negotiating to put that fight together.

"It's so hard to get an opponent in the ring with Gennady. If I stopped working with certain people, it'd be even less.

"Danny Jacobs had a tremendous win over Peter Quillin with a first round knockout. Gennady sold out Madison Square Garden and Jacobs is from New York. That's just one off the top of my head that would be a great match-up.

"Naturally, the focus is on Canelo. If everything goes the right way with the fight with Wade, or unifying with [WBO champion] Billy Joe Saunders. If one of those fights can't get made, the Jacobs fight is a huge fight for the middleweight division."

Alvarez won the vacant WBC crown when he comfortably outpointed Puerto Rican Miguel Cotto in November 2015 and will be making his maiden defence against former super-lightweight champion Khan.

Golovkin is enthusiastic over the prospect of adding more titles to his collection and told behindthegloves.com: "I want a unification fight. It doesn't matter with who, I'm ready. I feel great.

"Absolutely, I'm ready. Right now my focus is on Dominic Wade, because he's the IBF mandatory challenger. I respect the mandatory challenger.

"Right now I'm to Canelo, the mandatory challenger. I think he's very correct like me. I think it's good for both, for business, for Canelo, for Khan. For money, why not?"
