Curtis became the youngest ever outfield player for the club when he made his debut as a substitute in a league game at Peterborough in May 2008 when he was still a month short of his 16th birthday. He then became the club's youngest ever goalscorer when he scored the winning goal against Grimsby in February 2009, and he scored another goal against Aldershot a month later. Several clubs from higher up the ladder are keeping an eye on his progress.
