remember to take the airport ticket it cost 2 not 1 otherwise when you'll arrive in Barajas you need to take an extra ticket( but with any file) for exit
According to my Madrid City Guide.. the extra Euro supplement is from T4 only.
Santiago Bernabeu is on the Metro 10 line. One stop from Neuvos Ministerios.
Metro line 8 is the train line that goes to/from the airport.
So take Line 8 to Neuvos Ministerios ( last stop from the airport), change to Line 10 North for Santiago Bernabeu.
Reverse to go to the airport.
--------------------------------------
If you are in or about Plaza Mayor with the gang partying before the match....
Go to Sol tube station and take Line 1 north to Tribunal and change to Line 10 north for Santiago Bernabeu.
If you miss that stop, continue on to the Plaza de Castillo stop and take line 10 south from there to Santiago Bernabeu.

Anyone in Madrid that knows the Metro can update if i'm wrong.
