Andorra is about 2 hours' drive up to the Pyrenees and is a fun and interesting place to spend a couple of days. You can stop in several cool small villages along the way. Much better than going up into France. Other options for a short trip would be Cadaqués and Figures up to the north. Loads of culture with the Dalí museums, and a different pace than BCN.

WRT the FCB game, they're playing Málaga. I wouldn't expect excessive amounts of drunkeness.
