Sixteen days separate Anthony Joshua from the biggest fight of his boxing career.He takes on Wladimir Klitschko on April 29 at Wembley Stadium, where he will defend his IBF heavyweight title for the third time in front of a record audience.Around 90,000 fans will be in attendance to watch and, with just over two weeks remaining until the bout, the mind games have well and truly begun.Whereas Joshua has been typically humble and focused in the build-up, Klitschko fired a warning to the 27-year-old earlier this week."Please excuse me as this may sound arrogant," the Ukrainian told the Independent, "but, for example, a parallel: Mount Everest. The highest mountain in the world."You can get to the top and say 'I conquered Everest!' Then you've got to run down because it's going to take you down if you miss the time."A lot of people died there. Some made it, not many, but some made it back. But Mount Everest is still there. It's still there and it's going to take another life this April."Very rarely does one boxing match create so much hype, with the final batch of tickets for Joshua-Klitschko selling out in just 25 minutes in February.Even Carl Froch couldn't get tickets for the fight when he popped to a kiosk recently, as you can see in the hilarious video below.Froch has constantly reminded people of how his rematch with George Groves in 2014 broke attendance records with 80,000, even bragging to Floyd Mayweather once upon a time.But when he asked for tickets to see Joshua-Klitschko at the kiosk, much to his dismay, he was told all 90,000 tickets has been sold - and his reaction was brilliant. Check it out.

Froch approached the kiosk and said: "How's it going mate? Can I get two tickets for the Joshua-Klitschko fight?" to which the attendant responded: "No, they're sold out."

"Sold out are they?" Froch replied, "80,000 have been sold?" 

The 39-year-old was told the attendance is in fact 90,000. He then said: "90,000? Is that the correct figure you've got there? All sold? Not available? Okay, fair enough," before walking away.

But Froch wasn't finished. He quickly returned and hilariously brought up his fight with Groves in front of 80,000 people.

"Did you know that I boxed here?" Froch said, "80,000 with George Groves," but the attendant insisted he didn't know who he was and repeated that all 90,000 tickets had been sold for Joshua-Klitschko.

Froch may have been the winner at Wembley three years ago, but he most certainly wasn't on this occasion.
