Mateusz Masternak has told Tony Bellew to forget about trying to intimidate him ahead of their crucial cruiserweight clash.
The Pole will battle Bellew for the vacant European cruiserweight title on the undercard of Anthony Joshua's grudge fight with Dillian Whyte at the O2 this Saturday, live on Sky Sports Box Office.
Bellew is one of Britain's most outspoken fighters and has been involved in a string of fiery exchanges with past opponents.
But Masternak insists the Merseysider will be wasting his time if he attempts to unsettle him as they come face-to-face during fight week.
"I've seen Bellew try to intimidate his opponents before but I'm sure he's clever enough not to attempt this with me," said Masternak.
"This sort of empty aggression and trash talking has no effect on me. Instead of trying to fight me at the press conference or the weigh-in, Bellew should save his strength, because he will need it in the ring!"
The 28-year-old, nicknamed 'The Master', does hold genuine respect for Bellew, who has only lost twice, with both of those defeats coming at world title level.

Masternak holds ambitions of his own and plans to make his name in Britain by dishing out a third setback to Bellew.
"This is a chance for me to test myself against one of the best fighters in the division and prove to everybody that I'm ready to fight for the world title," he said.
"Bellew is a world-class opponent and I know it will be a tough test. He can punch, he can box and he always fights with a lot of heart, but his style suits me well, and my team and I have chosen the perfect game plan to beat him.
"I will be like his shadow - staying one-step and one-punch ahead of him at all times. If he thinks this will be an easy fight, he is mistaken.
"This is a fight I have to win. I will give it my all and not stop until my hand is raised. I believe this will be the fight of the night, and once it's over, everyone will know the name Mateusz Masternak."
