Hi Shaun,
Here's a link to the ticket prices
http://www.realmadrid.com/web_realmadrid...=4&subsec=3 The prices are pretty good and a lot less than you'd pay at Bramall Lane, or dare I say it,
Hillsborough!! They start at 12 Euros for a seat in the stand I sat in last time I was there... mind you, you need a good head for heights there and an oxygen tank for reviving yourself halfway up the circular climb to the top!!
The Villareal game is virtually sold out anyway, apart from a few tickets left that are reserved for members.
Tickets for the Roma match go on sale at the stadium on Monday and Tuesday next week from 3 until 9pm and then on the day of the match from 11am. I wouldn't have thought it would sell out, but then I could be wrong, so I would get along to the Santiago Bernabeu as soon as possible. Have lunch at the bar across the road from the north end of the ground. I can't remember the name of it, but all the paintwork is green and it's on two levels. Food and drink excellent and good prices too. Even on match days no problem getting served. Enjoy the game!
