Possible New Look for the Santiago Bernabéu.

Looks awesome!
IMO: #1(Top Left) or #2 (Top Right)

If the club is driven by style and futuristic looks, then I guess #1 is okay. 

Of course Real Madrid is a very successful club, but football itself shouldn't be driven too much by money, and #1 looks to be exactly like that; too much details have been put into this design and the variety of colours looks too extreme. #2, on the other hand, looks rather odd because of the red lights. I don't understand why it needs to be red, since I don't see any connection, whatsoever, with it to a club that made the colour 'white' it's symbolic colour, plus the stadium looks like a giant UFO. #3 looks to be the most normal design of them all, but it looks a bit weird with the name "Real Madrid" on top, which leaves me to #4.

I think #4 looks most suitable for Real Madrid. The club should go for what looks to be most symbolic, not for what looks most fancy. Personally, I think #4 gives brings out more meaning to the club than the rest.  It's white, which is RM's iconic colour. The club is also known as "El Galactico" (or something), right? If you think about it, the simple, plain and oval design of the stadium, with the white light centre, looks to be imitating the actual shape of a galaxy. How mesmerizing....Plus the blue lighting around it blends in with the white quite well, I like that. Simplicity is aesthetically beautiful to me (not to sounds like a fag). So for me, it's #4 any day. 

It isnt red coz in the pic I posted, its blue. I think its something like Allianz Arena, where they change the colour theme depending on the fixture !!

Its Los Galacticos, but if you were emphasizing on white as the symbol, then the name is Los Blancos.
Galacticos is a very recent name given due to the Club's heavy spendings !!

I go for 2nd and 4th !!

2nd for its design (not to consider the red colour as it is blue in mine pic)

I was typing mine while man_utd's post was only present, but yeah, I'm still sticking with #4

I think #3 looks a bit like Nou-Mestalla. I think #1 looks nices for them. 
Off topic but What ever happened to the 1billion resort they were building?

its going on , will be done till 2016.... I dont really get why spend that much on a resort when you can spend that money in spain's betterment or setting a youth development base in asia or somewhere!!

It's being built in Ras Al Khaimah so I will be close to it since I'm in Dubai :P

On Man_Utd's one, i prefer the bottom left. It's the only one that look's real.

looks real!? They said the same stuff about Alianz Arena, that Alianz Arena looked to unreal. but it was built...

I'm so excited about naman's 3rd one.

@expert: my and man_utd"s pics are same ..... but from different angles. these are officialy the only four possibilities.

But still if this possibility would be taken, it will be a revolution for modern football.

The bottom left one (on Man_utd's post) looks awesome. Not sure about the rest.

the very first picture is probably nicest for me.

Sick! #1 is extremely cool, #2 is a very unique design, and #4 reminds me a little of the Emirates Stadium.
