Barcelona thumped Real Betis to go top of La Liga and extend their unbeaten run to five matches on Saturday at the Olympic Stadium in Montjuïc, Catalonia, in the fifth round of the Spanish League. Portugal forward Joao Felix, who is on loan from Atletico Madrid, scored his first Barcelona goal in an impressive display at the Nou Camp. Robert Lewandowski, Ferran Torres, Raphinha, and Joao Cancelo were also on target for the champions. Barcelona are a point ahead of Real Madrid, who host Real Sociedad on Sunday. Barcelona had 66% of possession and created passing intricate moves to break down a Betis side whose best chance came when Willian Jose was denied from close range by goalkeeper Marc-Andre Ter Stegen. Betis, who travel to Rangers in the Europa League on Thursday, are ninth in the table. Barcelona provisionally moved top of the La Liga standings with 13 points, while Real Betis ranks seventh with 7 points.
