Kell Brook has issued a statement asking Amir Khan to step up and meet him in the ring next year, reports Sky Sports.
The 30-year-old has returned to the gym after losing to Middleweight Champion Gennady Golovkin at the O2 back in September.
Sustaining a fractured eye socket injury during the fifth-round stoppage loss, the IBF World Welterweight Champion recently urged long-time rival Khan to finally put his money where his mouth is and accept the invitation.

Khan has previously stated that an all-British encounter would only happen at welterweight.
Brook is eager for the talking to stop, labeling the 29-year-old "Amir Khandashian" after the TV celebrity family, claiming that his focus could switch to other champions in the 147lbs division.
The Brit said: "With got some big names, Amir Khandashian, he's still there.
"People are talking about us fighting, he's said he wants to have that fight and like I have said, I'll meet him at welterweight if he actually wants to get in and stop talking about it."
The boxer added: "We need to sit down, get it signed and get it done for the fans.
"Manny Pacquiao, Danny Garcia and Keith Thurman are fighting and I am top of that pile, I am looking forward to getting a top fight made."
Unbeaten American Errol Spence is the mandatory challenger for the IBF title, but Brook wishes to unify the division, pointing to a potential future clash with newly-crowned WBO Champion Manny Pacquiao.
Pacquiao returned from a seven-month hiatus to defeat Jessie Vargas in Las Vegas to clinch the title for the third time in his illustrious career.
Asked about facing the multi-weight champion, Brook said: "I'd love that. I heard that I inspired him during the Golovkin fight and it makes sense for us to unify the division at welterweight."
The retired Floyd Mayweather watched from ringside as Pacquiao won with an unanimous decision, and Brook believes that the American could return to the ring.
Brook concluded: "I can definitely see him coming back. He's not training and being at these fights for no reason, he's going to come back, and he's just biding his time."
"I am just excited and privileged I am a champion amongst those names in the welterweight division, my name and profile has risen quite highly after the Golovkin fight.
"I am looking forward to training hard and hopefully a big massive name will come along."
