EDIT: See comments, I misunderstood the purpose of the question. It's difficult to understand, especially the first sentence. "[...] to say". To say what? Or do you mean something else? If you expressed it differently in English, or perhaps wrote the original sentence in Bosnian, then perhaps I could better understand it. There are also some other grammatical issues, but they can probably wait. "Beaten that WHICH is almost invincible" make sense though. But the word "which" is important there.
