Results since Robertson has arrived are about as indicative of his ability as are possession stats of our ability of a team.
He's come into the team in a difficult position having lost our manager and performances on the slide, the fans turning against the club and not match fit. Since then he has improved steadily and already become an important member of the squad, easily performing better than Bostock and Austin.
He is 22 and still learning his trade. Put him alongside Palmer and a fit for purpose defence after a full preseason and he will prove himself.
