Moore made his Derby County debut on 25 September 2010 against Crystal Palace, coming on as 74th minutes substitute, in a 5–0 win. Moore was primarily used as a substitute in at the start of his spell at "The Rams", 3 of his 4 appearances coming as substitute, but impressed enough for Derby boss Nigel Clough to want to extent his spell at Pride Park. The same day as Clough announced his desire to retain Moore's services, he scored his first goal for the club, on his second start, with the opener in a 3–2 victory at Doncaster Rovers. The next week, it was announced his Derby loan had been extended for a further month, the loan was further extended to the end of December.
