看守領隊
In November 2008 when Alan Pardew left Charlton by mutual consent, Kinsella left his post as Reserve team manager, being replaced by U18 Youth Coach Damian Matthew, to adopt a more senior role in the first team, helping Caretaker manager Phil Parkinson, while a replacement for Pardew was found. In December 2008, Parkinson was confirmed as the new Charlton manager, and Kinsella assumed the role of first-team coach permanently. He was sacked along with Phil Parkinson on 4 January 2011. He was linked with return to his former club Colchester United as manager in August 2009, but the job went to Adrian Boothroyd.
