Lionel Messi scored one penalty and missed another as his double helped Barcelona sweep Levante aside in the second half in a 4-1 victory to maintain their perfect La Liga start.
Defender Marc Bartra showed composure to open the scoring by converting a Messi cross after 50 minutes with Barca having been frustrated in the first half by a well organised Levante side.
With the game having opened up, Neymar finished clinically after 55 minutes and won a penalty on the hour which was converted by Messi.

At the other end, Barcelona goalkeeper Marc-Andre Ter Stegen flapped at a cross that allowed Victor Casadesus to slot the ball home after 65 minutes.
Messi blazed a second penalty over the bar after he himself was fouled but the Argentine did score again with a drive from the edge of the area a minute from time.
Last season's treble winners lead the standings with 12 points ahead of three teams, including arch rivals Real Madrid, on 10, having won all of their four games so far.
