hmmm someone asked that very question before!! Moving this to the Cancun Info. section, you will have better luck there!
Do you know which hotel you are staying at for your trip yet? A lot of the hotels will show Premier League and international games like the World Cup and such. Bars that are frequented by locals will usually show Mexican League football as well.
Corona Bar showed Man U vs Middlesboro FA Cup game while i was there last march so i presume they show more
balls to the footy your in mexico if youve got time to watch football you got no place on spring break lol
