World heavyweight champion Wladimir Klitschko has brushed off the latest extreme efforts by USA boxer Shannon Briggs on Wednesday to earn a shot at the Ukrainian's belts.
US boxer Shannon Briggs tries to enter the venue where Ukrainian boxer Wladimir Klitschko and Kubrat Pulev of Bulgaria were to meet for a public training session on November 12, 2014 in Hamburg, northern Germany
Briggs, 42, gate-crashed Klitschko's opening training session in Hamburg, as he prepares for Saturday's world title bout against Bulgaria's Kubrat Pulev, before being ejected from the building by security guards.
"The people don't want Klitschko anymore. Champ, come out at last," bellowed the American in his latest effort to get a world title fight with Klitschko.
"I'm the real champ. The world wants to see the Klitschko-Briggs fight.
"I'll knock Klitschko's teeth out."
Briggs then peeled off his shirt and pounded his fists on the building's glass doors, demanding: "Give me something to eat!"
This is not the first time Briggs has gone to extreme measures to get Klitschko's attention.
He gate crashed the press conference before Klitschko's last fight against Australia's Alex Leapai in April, then a scuffle broke out when Briggs approached Klitschko while he was eating in an Italian restaurant in Miami.
He even taunted Klitschko, the WBO, IBF, IBO and WBA champion, from a speedboat while the Ukrainian was stand-up paddle surfing in Florida.
"I really couldn't care less what he does," said Klitschko, 38, after Briggs' latest stunt.
"I will just concentrate on the fight."
Briggs, who has twice held world titles, is undefeated in his last six heavyweight bouts since losing to Vitali Klitschko for the WBC title in Berlin in October 2010.
Klitschko's fight against Pulev in Hamburg will be his 17th defence of his world titles, having held at least the IBF belt since 2006, but his Bulgarian opponent is unbeaten with 11 knock-outs in 20 victories on his unblemished record.
