Let me re-phrase the question, which ESPN channels does Claro have? Since ESPN has the contract rights, I would assume the games will be on ESPN Deportes and/or any other ESPN channels that Claro has.
unfortunately we may not know until the day the euro matches start exactly which channels will broadcast the games.....i say that because when one or two of the local channels has the "rights" they sometimes put a block on the international channels. just get black screens.
