Will be happy if he can prove me wrong but Zouma is basically another Cahill, IMO. Good and solid in defensive systems but found wanting in more progressive, attacking systems. Positionally poor, not great intelligence in higher defensive line and offers average, unambitious passing when on the ball. As Vesper mentioned above, I'd rather go with Luiz and Christensen at Old Trafford. At least they have decent chemistry by now having played together last season along with the full backs.
