I wondered earlier if team territory percentage was a significant predictor of winning percentage – obviously, it should be, but there's no guarantee that the data is collected correctly. At any rate, the answer is yes:
I'm comparing territorial control to the percentage of shots taken by a given team [=SF/(SF+SA)], which is itself a good proxy for goal differential and winning percentage. The four points up at the top right are, not surprisingly, Chelsea, Man United, Liverpool and Arsenal.
