Kell Brook's promoter Eddie Hearn is confident the Sheffield fighter and Amir Khan will face off in a much-anticipated world title showdown next summer.
IBF welterweight champion Brook has long courted a bout with Khan, who has snubbed his British rival on several occasions in an effort to lure pound-for-pound superstars Floyd Mayweather or Manny Pacquiao into the ring.
But with Mayweather now retired and Pacquiao reportedly set to turn down Khan's overtures, the Bolton fighter is now apparently keen to take on Brook.
Hearn told Sky Sports: "We're pushing forward for the Amir Khan fight and we expect it to happen at the end of May or early June.
"We're speaking to their team and I believe the fight will happen. It's the biggest fight out there for both of them. It's common sense and I believe common sense will prevail."
Brook may make a mandatory defence of his world title against little-known Canadian Kevin Bizier in the meantime.
The 29-year-old (35-0, with 24 knockout wins) has not fought since stopping Frankie Gavin in May and pulled out of an October date with Diego Chaves due to a rib injury.
Hearn added: "The IBF have ordered us to fight Bizier. We had an agreement to fight Chaves but if the fight's not for the IBF world title then the agreement is void.
"If we have to deal with the mandatory then it's likely we'll travel to America to do it because it's more appealing there than here.
"He's a decent fighter but it's not the easiest to sell and we need to prepare for the Khan fight, which is what we're heading towards. It's all feet to the pedal on that."
