Thierry Henry scored a hat-trick to steer Barcelona to a 4-1 win at bottom club Levante in the Primera Liga on Saturday.
The France striker notched his first Barca goal in the 3-0 victory over Olympique Lyon in the Champions League last week and broke his Primera Liga duck with two early goals against Levante.
Henry completed his hat-trick just after the restart and almost immediately Argentina's Lionel Messi made it four.
Levante pulled one back from the penalty spot through Emilio Viqueiria but offered little threat. Barca's first away win put them top of the table with 14 points from six games, one ahead of Real Madrid who visit struggling Getafe on Sunday.
Earlier, Real Zaragoza condemned Sevilla to their fourth consecutive defeat after winning 2-0.
Argentine midfielder Andres D'Alessandro opened the scoring for the hosts with a free kick early in the second half and, as Sevilla pressed forward, striker Sergio Garcia caught them on the break at the end.
The UEFA Cup holders, who missed enough chances to claim all three points, were beaten by Arsenal in the Champions League last week and have since lost three Primera Liga matches.
It is the first time since 1999-2000, when the side were relegated, the Andalucians have lost four on the trot.
Zaragoza climbed to eighth with eight points from six games while Sevilla slipped to 11th with six points from five.
