A goal in each half saw Birkirkara ease past Gudja United to go top of the BOV Premiership, a point above Hibernians who play Sliema Wanderers on Sunday.
Both sides ended the match with ten players.
Two excellent free kicks by Leandro Aquirre, the first after ten minutes and the second in extra time after the 90 minute mark sent B’Kara to the top of the table.
