Lionel Messi scored a hat-trick, with two stunning free-kicks, as Barcelona saw off Celta Vigo 4-1 at the Nou Camp to regain top spot in LaLiga.
Messi set Barca on their way with a penalty, but Lucas Olaza equalised with a fine free-kick for Celta's first goal under new boss Oscar Garcia.
The Barcelona number 10, though, soon had his side back in front just before half-time when he crashed home another superb deadball strike.
Messi completed his treble early in the second half, clipping the ball up and over the wall from 25 yards, and Sergio Busquets crashed in a late fourth.
