Unbelievable game which left Marco Kurz furious. Just heard ref apparently didn't toss the coin to see which end the penalty shootout would be held as in IFAB Law 10. FFA according to sources wanted it to happen at northern end in front of the Glory shed. #PERvADL

Other considerations?
Unless there are other considerations (e.g. ground conditions, safety etc.), the referee tosses a coin to decide the goal at which the kicks will be taken
