UEFA have demanded a full report from the Portuguese Football Federation over allegations of bribery and match rigging in a Cup Winners' Cup game 12 years ago.
Fernando Barata, the former coach of first division side Farense, admitted this week that he acted as a go-between to bribe a Romanian referee when FC Porto beat Aberdeen in the 1984 semi-final of the competition when Alex Ferguson was in charge of the Scottish holders of the title.
Barata said that he paid the referee before the first-leg game, which the Portuguese club won 1-0, at the request of Porto chairman Jorge Nuno Pinto da Costa, who denies the charge. Porto went on to lose the final 2-1 to Juventus.
UEFA's head of international competition, Rene Eberle, has asked the Portuguese federation to respond to the allegation that Pinto da Costa rigged the match.
Eberle said that UEFA could not annul a result after 10 years, but it could recommend that international ruling body FIFA punish clubs for corrupt practices.
