I probably should have hijacked the football thread to ask this, but anyway, here goes:
Has anyone here ever gone to see a La Liga match without buying a ticket beforehand? Specifically, I want to go and see Athletic Bilbao vs Barcelona on April 28th, but I can see no way of buying a ticket online unless it's some weird third party rip-off merchant. The Bilbao website doesn't sell tickets and the only helpful thing I've found is something on Trip Advisor saying you can only buy them up to 2 days in advance from the stadium.
Basically, if I rock up in Bilbao the day before, d'ya think I'll be able to get a couple of tickets?
