I have more posts to reply about height.
I have just clicked "mentions" on my profile to see who is trolling after Roma.
Anyway, about your post, I hope that you do know that an average height is higher and higher in each decade due to a different food and modern era.
Check here, for example:
https://ourworldindata.org/human-height
So, guys in 60s who were winning trophies, were born around 1940'.
An average height in France for guys born in 1940 was 171,7.
For example, if you were a 180cm in 60s, you were among tallest guys.
If you were 190cm then, you were a giant.
While, if you are 180cm today, you are average in Europe. Or, with 180cm, you are below average in Scandinavia, Netherlands, Southern-East part of Europe (Croatia, Montenegro, Serbia etc).
And 190cm is somewhat above average in Europe, but not as tall in 1960s.
So, Real's guys were quite taller than the average guys then.
By 1980, an average height raised to 176,5 cm in France.
And in the last couple of decades, it exploded way faster than before.
So, you can add freely 2-3 cms for years between 1980 and let's say 1990-1995.
That means that those Real's players would be 7-8 cm taller today, in a current era.
So, basically, these players which you mentioned actually had:
179
185
178
186
186
So, more or less, you proved my theory that you need to have at least average height and strength to dominate a CL.
So, thanks for proving my theory.
RM won 5 CLs in a row with players who were way above average height for that era.
