Ha, apologies, I never saw this topic.
But for future reference, Ireland relies heavily on British networks for it's soccer coverage. You will NEVER find Calcio in Ireland unless it on British Sky and for now at least, that is not the case as far as I am aware.
The only way you can get Calcio in Ireland is via Pay Per View and the only places that have that are pubs. Unless you can walk into a bar and nicely convince the barman to put on the game, you have absolutely no chance of finding Lazio games. And even then, there is no guarantee that Lazio will be the featured game.
Internet is the only viable way of finding Lazio games here.
