Eh? Most players have sporadic sprints, jogs, walks and phases where they merely hold position, while Ozil is constantly in the category between walk and jog, for the entire 90 minutes aside from about 5 times a game where he sprints. Part of that is due to his position, constantly trying to find space, and having teammates run ahead of him to exploit his passing.
A lot of the time it seems like genuine laziness though
It's not laziness, his lungs are black.
