I live in Italy, so I cannot avoid being a football fan aswell (Milan! like Djokovic ).. I think the "football" I mean is what you in USA call "soccer" :P but I'll give a shot to Volley World Cup and, if they'll start, some NBA (go Celtics ) and maybe some Ski World Cup. I watch many sports so I might have missed something to say.
The only sport that has ever interested me enough to watch on TV is Tennis.... so I wont be watching any other sports. Team sports are boring imo..... the 1v1 format of Tennis is much, much more interesting to watch.
