Barcelona secured their place in the last 16 of the King's Cup yesterday despite being held to a 2-2 draw by third division Alcoyano at the Nou Camp.
Barca, who held a comfortable 3-0 advantage after the first leg, put the result of the tie beyond doubt when reserve forward Santiago Ezquerro struck twice in the first 11 minutes.
But a penalty from Perona and a last-minute strike from Arnau earned their modest opponents a rare draw at the Barcelona stadium.
Last year's losing finalists Getafe cruised into the last 16 after a 4-1 win at home to Burgos earned them an emphatic 5-1 victory on aggregate.
