Depends whereabouts, it's quite a big pace with loads of pubs and bars, I would say that most of them in and around the town centre will be showing it, The Belle Vue on Whitegate Drive is OK, not bad food either (if your into cheap pub grub)

The Hop Inn near Talbot Road Car park (and the Train Station) always shows games
But like I said most places will have it on, there are quite a few City fans on the Fylde
