Raphinha and Lamine Yamal scored twice each as Barcelona returned to the top of La Liga with a convincing 5-2 victory over Rayo Vallecano at the Nou Camp.
Rayo, still searching for their first win of the season, stunned the home crowd when Sergio Camello put the visitors ahead after 12 minutes. Barcelona quickly responded, with Raphinha equalizing before Yamal put the hosts in front with 21 minutes played.
Florian Lejeune's own goal early in the second half gave Barcelona breathing room, but Camello struck again to keep Rayo within touching distance.
Raphinha restored Barcelona's two-goal advantage before Yamal completed his brace, securing a fourth consecutive victory and preserving the champions' perfect start to the campaign.
Rayo had arrived at the Nou Camp without a win in their opening two matches but showed little fear against their more illustrious opponents. They took the game to Barcelona early on and were rewarded when Camello fired into the bottom corner after Alvaro Garcia's well-weighted pullback.
