Nathan Cleverly says he's fired up and ready to knock-out Karo Murat after the German accused him of being gobby.
The pair clash in an Eliminator for the WBO World Light-Heavyweight title at the LG Arena, Birmingham, on September 18 on Frank Warren's huge Magnificent Seven event, live on Sky Box Office.
Undefeated Murat stoked the flames ahead of their fight by laying into the Welshman.
Warning him that he was "no Joe Calzaghe", Murat said that Cleverly was nothing more than a "big talker" and should keep his mouth shut.
But the unbeaten European champion - who also holds the British belt - has fired a verbal warning across the channel.
"Joe was probably one of the best fighters to ever come of out of Britain and I've never claimed to be as good as him.
"I've had the best schooling by training and sparring with Joe for so many years, but now it's my time to break through and become a big name " said 23-year-old Cleverly.
"One thing that Calzaghe did was knock out a German in the first round, and I definitely want to follow in his footsteps with regard to that!
"To me, it looks like Murat is the one who's got a big mouth, but I'll shut it for him when we get it on."
Murat also said that British fans will love him because they like exciting boxers.
But Cleverly had an answer to that too.
"British fans are the best in the world, and they will get behind you if you are any good," he said.
"But the one thing they like more than an exciting boxer is a German who is flat on his back, and I'll deliver that for them on September 18."
