most English speaking people support two teams - their own and anyone playing Australia.

Back to leaders, I dont think it's at all easy to define the characteristics of a good leader. Taking as an example the invasion of Normandy and the subsequent actions up to VE Day, the three top men, Eisenhower, Montgomery and Patton were each entirely different in their approach to leadership, but were all undeniably effective.
