I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">football supporter</span>' is the definition.<br/ ><span class="explanation-format__explanation">(football fan)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for fan that I've seen before include "Ardent admirer" , "Cool - enthusiast" , "Cooling device for enthusiastic supporter" , "Cooling device for devoted follower?" , "Cooling device for an ardent supporter" .)
