MADRID, Jan 3 (Reuters) - Barcelona came back from a goal down to claim a 3-1 win over third division Zamora in the first leg of their King's Cup fifth-round tie on Tuesday, extending their winning streak to 14 matches in all competitions.
Unfancied Zamora, who knocked out Primera Liga Real Sociedad en route to the last 16, gave their illustrious opponents a run for their money and took a shock lead when midfielder Xaco steered home in the fifth minute.
Barca, without attacking trio Samuel Eto'o, Ronaldinho and Lionel Messi as well as influential midfielder Deco, were slow to respond but gradually began to gain control.
Dutch midfielder Giovanni van Bronckhorst levelled eight minutes before the break with a cool finish after a slick one-touch passing move involving Santi Ezquerro and Rafael Marquez.
Nine minutes before time Mexican midfielder Marquez put the Catalans in front when he curled an unstoppable free kick past the wall and into the far corner from 20 metres out.
The goal put an end to Zamora's brave resistance and winger Ludovic Giuly wrapped up with a third when he turned in at the near post after defender Silvinho had scorched his way down the left flank and squared the ball into the Frenchman's path.
Real Madrid are at struggling Athletic Bilbao in Tuesday's late match. The other first-leg games take place on Wednesday.
