Tyson Fury has launched a foul-mouted Twitter rant at David Haye and said that he would defeat him within "5/6 rounds".
Fury recently claimed that a fight with the Londoner was 99% done.
Following Fury's revelation, the unbeaten heavyweight took to his Twitter account to repeatedly insult the former WBA world champion.
"@mrdavidhaye I Want U Sucker so sign the contract & let me rip your F ing head off pretty boy!" Fury tweeted.
"@Mrdavidhaye u r gonna get it boy! Within 5/6 rounds spark out!"
The 25-year-old also reserved some verbal jousting for Ukrainian brothers Wladimir Klitschko and Vitali Klitschko, after stating that he wants to fight both after the purported bout with Haye.
"After I f**k up haymaker I'm gonna go get the klitchko sisters! & rid them of my division! @Mrdavidhaye @Klitschko @VitaliKlitschk0"
Haye recently claimed that a potential fight with Fury would be "fun".
