I thougtht you were talking about the Real Madrid - Bayer Munich match. For the "normal" league match there shouldn't be any problems to get tickets.
Dave, perhaps you can leave the luggage at the airport and quickly take a taxi to the stadium. It will take you about 20 minutes to arrive there. If you can't make it, then take the subway back to the airport to the left luggage that is near the station.
