When Kerry FC run out on Sunday next at Tallaght Stadium to face Shamrock Rovers in the FAI Cup, nobody will expect them to conquer the 25-time winners. 

It is the ultimate David v Goliath match-up, one that looked unlikely to occur when Sligo Rovers were coasting 3-0 in front on the hour mark in the quarter-final, thanks to an Owen Elding hat-trick.
