The 21-year-old academy product was out of contract this summer, after turning down a new deal with the Sky Blues, but Derby must still pay an undisclosed compensation fee, as he is under 23.
Despite his age, the Coventry-born right-back has amassed over 100 appearances for the financial stricken club since making his debut in August 2010 at the age of 17, and several Premier League and Championship sides were also thought to be weighing up offers for him this summer.
Having been linked to Tottenham Hotspur and Bolton Wanders in the past, reports of a potential MLS move in May came as a surprise, with manager Steven Pressley moving to blast Christie’s agent for what he labelled a ‘panic move’.
Nevertheless, Toronto FC, D.C. United and the New York Red Bulls were all said to be courting the highly-rated League One youngster, who would have become one of a number of Englishmen to make the move to the States over the past 12 months.
With Derby boss Steve McClaren desperately needing a new right-back however, following the return of Andre Wisdom to Liverpool upon completion of his season-long loan, Christie should be given amble opportunities to impress in the Championship, where he can continue his growth as one of the Football League’s most promising defenders.
