After a draw at Ploiești (1–1), "The Yellow Wolves" impressively beat Viktoria scoring four goals and conceding only one.[5] The Romanian side's captain, 35-year-old Adrian Mutu, played a big role in his team's qualification, scoring both home and away.[6] However, losing both of the play-off legs against Dinamo Zagreb of Croatia, Petrolul yet again missed the chance of advancing to the group stage.
