for a very short spell until October 2005, was former Inverness and Hearts manager John Robertson. He left the club on 24 October 2005, due to differences of opinion on a number of fundamental issues with the chairman. Gardner Spiers, a former Aberdeen coach, was appointed caretaker manager, but he too left in April 2006 after being told he would not be considered for appointment on a permanent basis. Director of Football George Adams took temporary charge before former Motherwell player Scott Leitch was appointed on 18 April 2006. Ross County won their first ever nationwide trophy when they won the Scottish Challenge Cup in November 2006 on penalties with Jason Crooks scoring the deciding spot kick on his competitive debut. Leitch, after winning the Challenge Cup but suffering relegation, stood down at the end of the 2006–07 season, almost exactly one year after his appointment. Former Partick Thistle manager Dick Campbell was announced as his replacement in May 2007. However, after a good run of results to start their Division 2 campaign, Campbell and the Ross County board decided to part company on 2 October 2007. Derek Adams (son of George Adams) took over as caretaker, and was confirmed as permanent manager a month later after the side's good form continued. County again reached the final of the Scottish Challenge Cup in 2008. They played Airdrie United at McDiarmid Park. Unlike two years previously, County lost in a penalty shootout where four penalties were missed. Ross County also reached the Challenge Cup final in April 2011 in which they beat Queen of the South 2–0. In November 2010 Derek Adams left to become Colin Calderwood's assistant at Hibernian. Former Celtic player Willie McStay was appointed as his replacement in November 2010. McStay's tenure was short – lasting only 9 games. Jimmy Calderwood was then appointed until the end of the 2010–11 season. In May 2011, it was announced that Derek Adams was to return as manager. On 23 March 2010, they defeated Scottish Premier League club Hibernian 2–1 in a Scottish Cup quarter-final replay at home at Victoria Park. In the semi-final, they played Celtic on Saturday 10 April 2010. In one of the biggest upsets in cup history, Ross County won 2–0 at Hampden Park and reached the final of the Scottish Cup for the first time in their history.
