Eddie Hearn is hoping the mega-fight between Kell Brook and Amir Khan will be confirmed before the end of January.
The Matchroom promoter admits talks are well underway, with Khan saying the fight “makes sense” for the British welterweight rivals.
Hearn is working closely with the Bolton star’s advisor Asif Vali and although he is refusing to look too far ahead, believes the deal could be done in a few weeks.
“There is still a way to go but it’s the obvious fight and talks are positive about finally making this a reality,” Hearn told Sky Sports.
“We are working hard behind the scenes with Asif Vali to try and get the fight over the line and hope for some good news in middle to late January.”
Khan says he will go back down to welterweight – where Brook still holds the IBF world title – after both losing their last fights at middleweight.
Khan was knocked out in the sixth round against Saul ‘Canelo’ Alvarez, while the Special One was stopped in four by Gennady Golovkin.
The pair are both expected to have a warm-up fight first, with the all-British showdown at 147lbs likely to happen towards the end of 2017.
There is no update with the venue, with Khan and Mayor of London, Sadiq Khan, both suggesting it needs to take place at Wembley Stadium.
