Defending champion Barcelona opened its La Liga season in dominant fashion Sunday, thrashing Elche 5-0 behind two goals each from Raphinha and Fermin Lopez.

Earlier in the day, Atletico Madrid fought back to secure a 2-2 draw with Villarreal, managing the stalemate despite playing down a man after Robin Le Normand was red-carded.

Fresh off Real Madrid's narrow 2-1 win over Espanyol under Jose Mourinho, Barcelona laid down a marker with a dominant victory against Elche.

Karim Adeyemi marked his debut with a goal while another debutant Anthony Gordon contributed a pair of assists, allowing Hansi Flick to smartly managed his squad by benching several key players recovering from the World Cup.

Even with a subdued performance from Lamine Yamal following Spain's tournament triumph, Barcelona's emphatic display showed they won't surrender their crown without a fight.
