If Chris Eubank Jr. wants his rematch next, Liam Smith acknowledged that he’ll have no choice but to honor that contractual clause.

If not, Smith pointed out during his post-fight press conference late Saturday night that he’ll have plenty of other appealing options now that he has become the first fighter to knock out Eubank. Liverpool’s Smith (33-3-1, 20 KOs) dropped Eubank twice in the fourth round and stopped the favored fighter in a Sky Sports Box Office main event at AO Arena in Manchester, England.

The 34-year-old Smith mentioned a domestic showdown with Kell Brook, which would take place at or near the junior middleweight limit of 154 pounds, and a shot at IBF/IBO/WBA middleweight champion Gennadiy Golovkin as alternatives to boxing Eubank next.

“He has to sit with his own team, his own family, and see if he wants this rematch,” Smith said. “But, you know, I’m open to anything, and I always have been. I always have been open to anything. And you ask anyone who has dealt with me over the years, I’m not a hard one to deal with. But, you know, if it’s Chris next, it’s Chris next.

“If not, we can sit down and I’ve got very good options now. I’m in a good position. You know, [BOXXER’s] Ben [Shalom] said Kell [Brook] wants to fight the winner. I know that’s a huge fight. I know there’s talks of [Gennadiy] Golovkin. So, I’m in a good position now at 160, as well as 154. So, you know, it’s again just a win that mattered [Saturday night].”

Shalom told Sky Sports last week that the 36-year-old Brook was “desperate” to fight the Eubank-Smith winner. Sheffield’s Brook (40-3, 28 KOs), who announced his retirement July 5, hasn’t fought since he stopped rival Amir Khan in the sixth round of their long-awaited grudge match last February 19 at AO Arena.

Kazakhstan’s Golovkin (42-2-1, 37 KOs) also is available. The 40-year-old Golovkin lost his third fight against rival Canelo Alvarez, who beat Golovkin by unanimous decision in their 12-round super middleweight championship match September 17 at T-Mobile Arena in Las Vegas, but Golovkin still owns three middleweight titles.

Smith, a former WBO junior middleweight champ, is willing to compete in the junior middleweight or middleweight divisions later this year.

Eubank (32-3, 23 KOs) informed Sky Sports during a post-fight interview in his locker room that he wants the rematch he is owed with Smith. The 33-year-old Brighton native also referred to Eubank-Smith II as a fight fans will want to see “further down the line,” which could allow Smith to face another opponent next.

“Listen, it’s boxing,” Eubank said. “It’s a sexy sport. This is the sport we love. Anything can happen. I never would’ve believed this could happen. I think, you know, a lot of people didn’t see this happening. But it happened. And that’s OK. I’m OK with it. You know, it’s a part of the journey. And I’ve still got a lot left, so we’ll see what happens later on in the year.”
