According to Allegri, Lang made a scene on the training pitch before the Champions League clash against Arsenal, reportedly over a misplaced pass by Antonio Vergara. This behaviour, Allegri said, led to Lang being left out of the team against the English side. Lang has since apologised and returned to the team, playing the full second half in Napoli's 2-1 win over Bologna last week.
VoetbalPrimeur reports that Allegri is expecting more from Lang, citing his abilities and qualities. "Given his qualities, he can and must bring more," Allegri said. "It's not easy to keep everyone fit throughout the season, so it's essential that those who are available perform well. If one player is injured, another must step in. But it's all about the right attitude and enthusiasm."
