This is event natal chart
It’s going to be an intense game (Moon in Scorpio) with a lot of controversy and probably a lot of mistakes by referees (Sun Neptune opposition). Real will actually play nicer football, but Barcelona is just one crazy team. They have a phenomenal compensation power (no earth or water in the chart – pure energy). Whatever they lack they will always find out the way to make it up.
I give advantage to Barcelona based on this Moon, Mars and Jupiter observations:
Both of them are very motivated. Both have Mars Pluto contacts – that’s what I looked first since the moon in Scorpio in the day of the event). With natal Jupiter in Scorpio Barcelona gets here 1 point from me.
Current Jupiter in Gemini may make Barcelona fight more eagerly with all this action in Sagittarius. Barcelona gets 1 more point from me.
Again Barcelona Mars is opposing current Jupiter, making them pretty motivated again.
The ruler of the chart you supplied is in the 12th house. That’s Neptune and it’s very strong in RM’s chart. Means typically a loss.
Barcelona was founded 29 November 1899. Strong fiery chart (Mars and Venus in Sag) with the moon in Libra:
Real Madrid was founded 6 March 1902:
