What is a 'dark horse' in sport?

Igor Thiago is described as an 'outsider' or a 'dark horse' in the Golden Boot race. This term refers to a competitor who is not expected to win but could potentially surprise everyone. Pundits often enjoy picking dark horses, as it adds excitement and shows their insight, much like Cascarino's choice of Thiago over more obvious contenders.
