If you ignore the blood-fams bit,there is a point to it.
Your fullbacks are gone and were gone even when they were there last season. Stones despite the English media touting it is not even close to a fit Kompany defensively.
You'll score bags of goals because Sanchez is the human equivalent of the duracell bunny but you'll still concede more than you want against Chelsea/Liverpool/Spurs/Utd.
You don't win the league if you let any of those 4 score against you home or away.
What happens if Kompany stays fit and City do an odd thing of signing new fullbacks due to having none?
