Jimmy Calderwood was Kilmarnock manager from January 2010 to May of the same year. He accepted the Killie manager's job on January 14th 2010, on an interim basis through the end of the 2009-10 season, guiding the struggling club to survival.
He won five of his first nine matches in charge of the club, including the memorable 1-0 defeat of Celtic on the evening Robbie Keane made his debut for the Parkhead men, but was unable to maintain that impressive early momentum. Kilmarnock managed just two more victories in their next 12 games under Calderwood.
The last of them a crucial 2-1 success against Aberdeen at Pittodrie in the penultimate fixture of the campaign which proved critical to their survival. His final match in charge of Kilmarnock, a 0-0 draw at home to Falkirk, where Killie preserved their top-flight status as they finished the SPL campaign two points ahead of their visitors. But while Calderwood achieved the minimum requirement made of him by Kilmarnock chairman Michael Johnston when he was appointed, his brief spell in charge neither damaged or enhanced his reputation.
Calderwood confirmed on May 31st 2010 he would not be returning to manage the club for the forthcoming season..... "I couldn't fulfill my ambitions under those financial limitations, To be honest, it was more to do with the budget and Sandy (Clark) leaving, To have a fighting chance of making the top half of the table, the budget wasn't enough. It would have made it very difficult to do that and take it on to another level."
