We watched the football when we were out there. Sometimes the games on setanta while some bars do have them, the pics are known to "freeze", we did however find one of the best places was Shadows bar (half way up the main street on the left handside if you walk away from the beach. Near to where they have the camels and opposite the chemist.
The other place that shows lots of footie and has plenty of seats etc is N-Joy.
They also put them on in our hotel, but we found it a much better atmosphere going down the main street. A lot of restaurants will show them, but will quite often have the volume turned down so you get pictures only. Definite thumbs up for shadows tho . . .great place anyway!
