Last month, Anthony Joshua (19-0, 19 KOs) packed in a record crowd of 90,000 fans to Wembley in London - when he unified the IBO, IBF, WBA heavyweight titles with a knockout of Wladimir Klitschko.
The capacity crowd broke the record set in 2014, when Carl Froch knocked out George Groves before a crowd of 80,000 in Wembley.
But there is another fighter from the UK who is confident in his ability to sell out the venue - former world champion Amir Khan (31-4, 19 KOs).
Khan has been out of the ring since last May, when he moved up to a catch-weight of 155-pounds and was knocked out by then WBC middleweight champion Saul "Canelo" Alvarez.
And the desired opponent for Khan in the other corner - IBF welterweight champion Kell Brook, who defends his title this Saturday night against mandatory challenger Errol Spence at Bramall Lane in Sheffield.
"There are very few fighters from this country that could fill Wembley, and I'm definitely one of them," Khan exclusively told Sky Sports. "Kell Brook would be a fight that everyone wants to see. I've been selling out arenas since I was 21-years-old when I first started topping bills. I was a pay-per-view fighter when I was 20."
Win or lose on Saturday, a Khan-Brook fight will still be there to be made. Khan underwent hand surgery last year which kept him on the shelf until early 2017. He was scheduled to face Manny Pacquiao in April, but their deal fell apart after the investors failed to present proof of the promised funds.
Khan wants to eventually come to the UK, head to Wembley, with Brook in the other corner.
"Come back to Britain, put on a big show, and beat someone like Kell in a rivalry fight. Who is No 1 in the division in the UK? People don't know who to pick, so let's prove it," Khan said.
