The chief of the home club has said there was foul play involved after 57 cables were cut leading to the cancellation of the Franjirrojos versus Los Blancos match
The clash in the Spanish capital, which was due to take place on Sunday, was put off by 24 hours - and has now been confirmed to be played at 19:45CET - after the lights at Estadio de Vallecas failed to operate and could not be immediately repaired.
Presa had last night told the Spanish media that "vandals" had sabotaged the wiring at the ground, and he has since endorsed his viewpoint by claiming that "football terrorism" was to blame for the problem.
"This is a new kind of terrorism, a football terrorism where a few prevent the fans attending a show," he told reporters at a press conference.
"About 19:00 yesterday, when we tested the lighting, technicians tested the lights and there was no lighting. Given this, the technicians went up to the stands to see what happened and realized that there were 57 cut wires. All of them were going to the mains.
"We have undertaken a special device to manage the crisis. At 09:00, the scientific police presented themselves at the club. Two and a half hours later they finished and gave way to a team of electricians who have worked to restore everything."
"This was made by someone who knew where to attack for maximum damage."
The club chief confirmed that the system will be tested later on Monday afternoon.
"At 15:00 there will be a test of ignition sources. It will be quite tedious, because we have to light them one by one.
"Unless a meteorite falls we'll be playing," he said.
