Some stats:
1. if Barcelona wins the CL, we will be hailed as the absolute kings of the last 10 Seasons with 4 trophies
2. if Bayern wins the CL, they will be the hailed as the European best team over the last few years
-- they would have wins in 2013, 2015 and finals in 2010 and 2012
-- the highest amount of finals in a short period in the last 20-ish years of CL
3. if Real wins it, they will win their 11th trophy
-- they will be the first team since 1989 and 1990 Seasons to win back to back trophies
-- also, if Real wins it, Spanish press will probably hail this success as greater than Barca's success with Pep, because Real needed only 2 years for 2 trophies
(Also, they will make a Goat out of Ronaldo)
So, whoever wins out of these 3 clubs, will be hailed as either the greatest team in the last 10 years (Barca), or the greatest European team in the last 5-6 years (Bayern) or the absolute European recorder and the first team to win back to back titles since 1990 (Real).
Whatever happens, we can expect a lot of hype and exaggeration.
(I don't expect Juve to win, so I won't write anything about that scenario, lol)
