A review of Tuesday night's action in the Spanish Primera Division.
Barcelona and Atletico Madrid continued their 100 per cent starts to the season as Neymar registered his first Primera Division goal in a 4-1 rout of Real Sociedad.
Sociedad hit the crossbar in the first minute but Barca then scored three times in quick succession to all but end the match before half an hour at the Nou Camp.
Summer signing Neymar, whose only previous goal for Barca was in the Spanish Supercopa against Atletico, opened the scoring in the fifth minute, Messi doubled the lead three minutes later and Sergio Busquets made it 3-0 in the 23rd minute.
Sociedad pulled a second-half goal back through Alberto De La Bella and briefly threatened to make further inroads, but they could not find another breakthrough and Barca wrapped up the scoring through substitute Marc Bartra with 13 minutes left.
The in-form Diego Costa was once again the key man for Atletico, scoring both their goals inside seven first-half minutes in a 2-1 victory over Osasuna.
Oriol Riera kept them honest for the second half after he struck just before the break, but Osasuna never threatened an equaliser to crash to their fifth defeat of a forgettable start.
Levante were left frustrated after being held to a 1-1 draw by 10-man Real Valladolid in their mid-table clash at Estadi Ciutat de Valencia.
A bad-tempered match saw one red and five yellow cards with Valladolid's French left-back Zakarya Bergdich given his marching orders in the 44th minute with the score at 1-1.
But Levante were unable to capitalise on playing half the match with an extra man with Andreas Ivanschitz Senegalfailing to convert a potentially match-winning penalty after Bergdich had gone.
The first half exploded into life 15 minutes from the interval when Levante surged ahead through Senengal striker Papa Baba Diawara, who swept the ball home from six yards out.
But their lead lasted just six minutes after veteran marksman Javi Guerra found the back of the net with a right-foot shot.
Finally, Fernando Tissone broke the deadlock in the 68th minute before Francisco Portillo scored in injury time to give Malaga a 2-0 win over Almeria.
