‘Special K’, boasting a professional record of 29-0 with 19 coming inside the distance, stopped Hector Saldivia in his home town of Sheffield last month to become mandatory challenger to the IBF welterweight title.
Later on that evening, Devon Alexander won the belt from Randall Bailey in New York and the showdown with Brook appears to be heading towards the first month of 2013 either in ‘The Big Apple’ or Las Vegas.
But Khan, who hopes to bounce back from two straight defeats to Lamont Peterson and Danny Garcia when he takes on the unbeaten Carlos Molina in Los Angeles on December 15, would love to be his compatriot’s first challenger should both emerge victorious in their next bouts.
“I think it's a great fight,” Khan told Boxing Scene. “I think it's a great step up for Brook because he has been fighting at a lower level.
“I'm surprised he's taking the fight with Devon Alexander. Devon Alexander is a great fighter. It is a great fight for the welterweight division and in the future I can fight the winner.
“If he gets past Devon Alexander, then I think it makes sense to have a fight with him.
“And he'll have a world title so it makes sense to fight Brook maybe in the UK - it would be huge.”
Khan will enter the ring against Molina next month for the first time under new trainer Virgil Hunter.
And the 26-3 Bolton fighter, who has engaged in wars of words with Brook in the past, knows that a third straight defeat would not only end his hopes of a grudge fight with ‘The Special One’ but perhaps his entire top-line fighting career.
“There’s always pressure when I fight but I definitely have to win this because if I lose, I’m done,” Khan admitted.
“This is a fight I need to win, 100 per cent. If I don’t win it I’m done. It’s that simple.
“The big super-fights I’ve always dreamed about won’t be there if I lose this. Pacquiao, Mayweather… forget it.”
Khan said of Hunter, who he brought in to replace Freddie Roach after being stopped by Garcia: “It’s a very tight community in that gym.
“You need to have people there you trust. Virgil keeps it very limited and that’s what I like about it.
“You’re not bothered about who’s watching, you’re not training for a crowd, or fans.”
