This season he's not. He has a rival from Poland now - Wojciech Nowicki, he even lost Polish National Champs to him. And Nowicki has the bronze from Rio. The same Rio where Fajdek didn't make it through the qualifiactions.
There are no dominants in Polish sports right now, I'm afraid. The closest to that is Anita Włodarczyk in Women's hammer but she has a very strong rivals from USA now, and when Russians are allowed to compete in full squad in Tokyo - there will be some strong players from Russia, too
But thanks for your belief in Fajdek - he's a nice and funny guy anyway
