I have no hard evidence, but I believe spinning the ball in your hands while approaching a set shot is a recipe for disaster.One small observation from the weekend was when he deviated from his usual set shot routine and started to spin the ball in his hands like Castagna used to. He then veered right, off his run up line like he was trying to hook his kick and needless to say missed the set shot.
He’s normally a very good kick for goal but must stick religiously to his set shot routine. He’ll be better for it.
