Draxler has actually only 28 caps not 38, so he's almost at average of 1 goal for every 10 games. In terms of GG he's at 9.33 GG, his stats are almost like looking at a very very poor NT, where you see players have like one handful of goals for like 30+ caps. as for Gotze, well we don't know how many games he played badly because of his illness. It does seem like it started at Bayern. That's when his form crashed too and you could clearly see his decline from there on.
