And what's the situation with Porto? Seems like 90% of their whole success was after the revolution...
Being older than average, I've seen the raising of the North team FCP.
First of all, I always remember them as the big team from the North. Although very strong, they usually failed to win when visiting the capital, seeming they were somehow psychologically affected. In addition, due the northern specific rivalry, they also used to lose lots of points when facing neighbor teams.
After the 1974 revolution, a huge economical crisis took place, and the North became the center of tradition. There were much less strikes in northern factories and overall business. That made northern teams take advantage of better sponsoring.
Among those, FC Porto, the biggest one, benefitted a lot form the whole situation, and their current president started a psychological flame war against the southern teams. He was only football responsible by then, and he also had one of the most experienced coaches.
The team was also very good, to be honest. As they are also very aggressive in the battle field (the grass, in this case), they succeeded in ending the 1977-1978 championship ahead of
SL Benfica in goal difference, thus wining the title after nineteen years.
A specific attribute of
SL Benfica is being bad losers, so the regulations were changed in order goal different wouldn't be the main criteria, but F C Porto succeeded in winning the title again next season.
This was the beginning of an era. Success brought money, and
seems they invested it bribing referees. Nobody was able to get enough proof so courts could convict them, but the whole country thought indeed the successive victories were fixed among walls...
A very late police affair almost did it, but phone talk recordings were at last not accepted as proof...
Anyway, meanwhile they got lots of titles, including European Champions Cup, UEFA Cup and Champions League...
They are the «bench mark», FWIW.
Nobody can win always, so a few titles escaped them, including 1979/1989 and 1981/1982 for Sporting.
