Wladimir Klitschko has firmly denied reports he was involved in a physical confrontation with Dereck Chisora in an Ibiza night club while on holiday.
A number of press reports on Tuesday suggested the two heavyweights were involved in a brawl in a night spot where bouncers were forced to intervene to split the pair.
Speaking to ATG Radio, 29-year-old Chisora openly spoke of the confrontation, confirming that the two exchanged words with the British fighter telling the Ukrainian, "I'm coming for you."
But the reigning WBA, WBO, IBO and IBF world heavyweight champion strongly denied suggestions the altercation descended into a scuffle.
"I'm shocked by media stories about an alleged brawl between myself and Chisora," Klitschko said through the Twitter account he shares with his brother, which was later published on the pair's official website.
"I am a pro fighter and let my fists talk only inside the ring.
"I don't want to comment on Chisora's psychological issues anymore."
I'm shocked by media stories about an alleged brawl between myself and Chisora. I'm a pro fighter & let my fists talk only inside the ring.

Chisora's previous run ins with the dominating Ukrainian brothers have been littered with controversy. The outspoken Brit slapped Vitali Klitschko during the weigh-in ahead of the their world title fight in February 2012, before spitting water in Wladimir's face moments before the same bout in Munich. He then brawled with fellow Brit David Haye during a post-fight press conference in what was a less than distinguished week for Chisora.
In addition to comments he made on ATG radio, Chisora has spoken of the alleged brawl between the two heavyweights, further underlining his desire to challenge one of the brothers in the near future.
"I can't say much about what happened in Ibiza but we were both there," Chisora told The Sun.
"Them brothers can never have a quiet holiday if I've got anything to do with it. But it's all in good fun, I can't complain.
"The best fight for them out there is me - the whole world is blasting for that fight. As long as his surname is Klitschko I'll kick his ass."
After stopping the unbeaten Malik Scott in the sixth at Wembley Arena earlier this month, Chisora is back on the world title hunt, which he will resume against an unnamed opponent at the Cooper Box Arena on 21 September.
Klitschko meanwhile is set to defend his world heavyweight crown against Alexander Povetkin on 5 October.
