Artur Szpilka is in buoyant mood ahead of challenging WBC world heavyweight champion Deontay Wilder on January 16.
The Pole (20-1-KO15) steps up in level when he travels to Brooklyn to take on the unbeaten Wilder (35-0-KO34), who will be making the third defence of the belt he won from Bermane Stiverne in January.
Having seized the opportunity when Vyacheslav Glazkov opted to fight for the world title the IBF stripped Tyson Fury of - and the underdog is confident of causing an upset as he continues his preparation by sparring the likes of former Wilder victim Eric Molina.
Szpilka, whose sole career defeat came to former world title challenge Bryant Jennings in January 2014, said: "I have had some really good sparring with Molina. Both of our trainers are impressed by what I can do and they tell me that if I box in the same way [when I face Wilder] as I'm doing in training - I should overcome Wilder.
"Molina is giving me some really good sparring... though he boxes a little different, a little wiser than Wilder.
"I'm tired after hard training, but I have a great diet and I get up at six in the morning to eat the first meal. We start quite early, because the training already beings at nine in the morning. I train hard and everything around seems to be beautiful.
"I realise that I can do something extraordinary and I am already looking forward to the day of the fight."
Should Wilder overcome Szpilka, a huge 2016 beckons with a possible unification bout against Tyson Fury already being touted.
