ESSEN, Germany, AAP - Alex Leapai is adamant his focus on the clash with heavyweight boxing world champion Wladimir Klitschko hasn't been diluted by the temptation to show some fistic fireworks a few days early.
Leapai was involved in a classic boxing sideshow when former WBO world champion Shannan Briggs gatecrashed a press conference in Dusseldorf yesterday.
The 42-year-old American who was put in hospital by Klitschko's brother Vitali three-and-a-half years ago, stormed into the room and delivered an eight-minute tirade.
He called Klitschko a pretender and a fabricated champion and angered Leapai with demeaning comments about the Australian.
"You're a bum, Leapai," Briggs yelled.
"Let's get it on right now. Matter of fact I don't want you, you're too small.
"I want him (Klitschko).
"I want nothing with you Leapai, you're just here for target practice for him."
Leapai moved forward on the stage and looked to be heading towards Briggs before being held back by Klitschko.
"I switched into Lionheart mode, I really wanted to fight him (Briggs)," Leapai told AAP.
"But Wladimir just told me 'look, our focus is our fight, just leave it at that', so I just left it at that."
The vastly experienced Klitschko said he had never seen anything like it.
