Your wrong with your first sentence. You can check goetze's tackles per match last season to see how many tackles he had even though he had long term injuries. Everybody in dortmund tackles, that high pressure is the most important part of klopps tactics. If someone leaves space for people to run through, then that wont go down well with klopp. I read somewhere before that reus and goetze had a combined 91 tackles last season. Mata wont work with his tactics unless he puts in some hard work.
