If you go down to the stadium on the day of the game as soon as the ticket office opens, usually at about 10-11 am, gate 42 on calle Concha Espina, there will be plenty of touts but do not buy off these as you will no doubt be ripped off.Last season we bought tickets in the tribuna section for 45 euro (£28), excellent seats plus Real beat Malaga 5-1, outside the touts were charging 50 euro for the 15 euro top tier seats. If you speak Spanish then you could also try the caja madrid number 902 324 324 about a week before the game, if it's Beckham's debut you might have trouble getting them though smile
