Chelsea manager Emma Hayes has deployed the right tactics while leading her team to its first Women’s Champions League final. And her psychological tools also have paid off. Before one match she showed her players a video of a female UFC champion repeating the phrase “I’m the best.” Hayes gives leadership lessons by encouraging players to learn from the way geese fly in formation and take turns at the front. The 44-year-old Hayes says “the best psychologist is the coach.” Hayes will be trying to become the first Englishwoman to coach a team to victory in the tournament when Chelsea faces Barcelona on Sunday in Sweden.
