Not all his fights were in Germany he fought in Austria once too, because he chose not to use his power much, which its clear he had from the Mundine fight, he would accumulate his punches to win rounds. I cant see any fights where i see he clearly lost but was gifted a decision. All fighters have close fights now and again, i dont see where you get the figure of 3 or 4 fights he shouldve lost.
He often had to fight through things like people cheating like Robin Reid hitting him with low blows and rabbit punches. He should have been disqualified!
