I can never hear about football tragedies without thinking of the Shankly saying. Hillsborough, Bradford City, Heysel, the Accra Sports Stadium deaths in Ghana in 2001, the dozens killed during Egypt's Port Said stadium clashes in 2012. The list goes on and on. Or indeed the recent depressing news of two more deaths during construction work on the stadium that will host the opening ceremony for next year's World Cup finals in Brazil.
As with all walks of life, constructive criticism should obviously be encouraged, but there is a clear difference between engaging in deserved, even frank, assessment, and pure bile and diatribe, the type of which that is increasingly populating the stands at home grounds, social media and hackneyed journalism.
