Four goals in an 18-minute blitz either side of half time helped the Catalans to their first win of 2019/20 against a Real Betis side who had won the equivalent fixture last season.
Griezmann, who had never scored a goal at Camp Nou for his previous club, Atletico Madrid, struck two fine efforts, a half-volley from a cross and a curling shot from outside the area – which he celebrated by throwing red and blue glitter over himself from his outstretched arms in a homage to his basketball hero LeBron James.
Barca’s biggest stars, Lionel Messi and Luis Suarez, weren’t fit to play and watched pitch side with their children.

Barca’s absences and last week’s opening defeat in Bilbao had left raised questions over hopes to win a ninth Spanish title in 12 years.
