Estrellero,
You pointed out the most important factor to me - neutral ground.
I used 1st as team I identified with Real Madrid - 7th as their opponeant - AMadrid.
Mercury called me back to past, my interest in cristiano ronaldo and his mad skills.
Neutral ground in foreign land - Milan - is 9th house with a neutral 7th house, because it wouldn't be 'neutral' if it wasn't 7th house - venus and sun bookend cusp of 7th in event chart.
I noticed the arab influence of the fans who like Real Madrid - I saw Sheiks in the white with blue - Iberian Peninsula - Portugal - the inbetween of arab world and europe. I have Iberian Peninsula and East Asian dna - so my bias for the Iberians might be an issue.
However, thank you for listening to my distraction while I thank you for your neutral ground chart. From it, a simple bit of mercury, is how I formed my accurate reading.
I usually look at outcomes from a variety of charts - event/natal/horary/transits, I like to think like an astology detective - forensics and all the usual suspects, so the more info the better.
Looking at Ronaldo's chart (in admitted bias) but regardless of bias, finding close 3rd house ties to game within his chart's acuario - looking at A Madrid's natal posted chart and also seeing the moon changes signs to square the team means everything starts over from the astro position - and in those cases, it's important to 'stick to the facts' - the forensic findings found in all the 'player's' charts.
