Coughlan wonder goal fires Gunners
The sides were level at 14 points apiece after an error-strewn hour but the Gunners made their move in the first period of extra time when they hit 1-4 without response.
Eight minutes in, Coughlan dashed into the red zone and looped the sliotar over the head of De La Salle defender Ian Flynn before retrieving it and firing into the bottom corner.
