Superstition also plays a part in games as important as the one in Munich.
That's why Real Madrid wanted to repeat their last (triumphant) visit to the Allianz Arena.
Last year they won there 2-1... the same as on Wednesday.
However, Real Madrid played in black only because Zinedine Zidane had made a special request to UEFA which was granted by the continental body.
But the 'obsession' to repeat the trip of 2017 didn't stop there.
Real stayed in the same hotel and asked to travel with the same crew that accompanied them to Munich.
Same result, same crew, same hotel, same colour of shirt... superstition worked
