Nick was City's showcase signing of the summer of 2012, arriving in July for the largest transfer fee the club had laid out outside of the Premier League era.

Although his career with the Tigers has got off to a slow start, he gave a glimpse of his talents when coming off the bench to hit a quick-fire double in October's 2-1 win against Ipswich.
