Mateusz Masternak believes he would have defeated Tony Bellew had the fight not taken place in Britain.
Next Saturday, Masternak will take on Chris Billam-Smith, and hopes to land the WBO cruiserweight championship belt in the process.
"Finally I have a chance," he told Sky Sports.
Masternak has plenty of experience since turning pro in 2006, and has fought contenders such as Bellew and Yuniel Dorticos. Both of those men went on to become world champions.
However, he thinks that had the fight against Bellew taken place in his native Poland, he would have won.
"It was a tough fight, close fight," he explained. "Tony won, maybe if I'd had the fight in Poland, I would have won. It happened in the UK so he won.
"I've had many great rivals in the past, like Tony Bellew, Grigory Drozd, Jean-Marc Mormeck, Dorticos, it's extremely difficult to say who was the most difficult one.
"I think every fight has let me progress. Against Tony Bellew I was inexperienced, but now I think that I am ready just to prove my skills, show my best and this is the time that I can get the title.”
He is under no illusion that Billam-Smith will also pose a tough test.
"Chris is a great fighter, he doesn't have a lot of weaknesses, in his last fight he was able to beat [Lawrence] Okolie. I have to watch him carefully and look at all his weaknesses," he said.
"The message to Chris and his fans is when I take the belt we're going to a Polish boxing event in London."
