Porto had no particular success last season - the "dragons" took 3rd place in the Portuguese championship, the team stopped at the 1/16 playoff stage in the UEFA Europa League, and Porto failed to advance from the group stage of the Club World Cup. Porto was active in the summer transfer window, significantly strengthening its roster.
Vitoria Guimaraes has significantly improved its results in recent years, regularly began to fight for European Cup places (last season the club reached the 1/8 playoff of the UEFA Conference League), but took 7th place in the championship, so this year the "conquerors" were left without European Cups. Vitoria cannot boast of a budget, so in the summer they signed only a couple of free agents, but the main players did not leave the team this summer.
Vitoria Guimaraes is a very serious opponent, but Porto is an obvious favorite at home.
