I've been thinking exactly the same. The wag possession is worked out doesn't really make sense to me.
It favours needless passing in areas that aren't dangerous, exactly like Villa and Wolves were doing and exactly what we ended up doing under Trollope.
Changes created, shots on target etc are much better indicators of how a team are performing in my eyes.
Possession bases football is good if done in the right way but possession for the sake of it masks team's deficiencies when looking at the stats and gives a good excuse after losing imo.
