Physically this guy has to be one of the best in Bundesliga. Fast and strong, I think BB could be raised to 86-87 range, thats something me and @oklahomastate010 talked about him. He has some communication problems but overall he has some much time to develop and become a really solid CB. Also he needs better Response, he might not be the best tackler but sure he is a responsive defender with sharp anticipation. Res could be at 79-80 range easily.
Better to die quick, fighting on your feet, than to live forever, begging on your knees!
