Barcelona and De Jong win big thanks to Griezmann. Antoine Griezmann helped FC Barcelona win the first league victory with two goals.
The defending champion won 5-2 against Real Betis in-house.
The Catalans had started in La Liga last week with a defeat at Athletic Bilbao.
Barcelona, with Frenkie de Jong, but without the still injured Lionel Messi and Luis Suárez, fell behind in Camp Nou.
Nabil Fekir, a teammate of Memphis Depay at Olympique Lyon last season, pushed the ball past goalkeeper Marc-André ter Stegen in the 15th minute.
Antoine Griezmann equalised with Barça before the break with his first league goal.
After the break, the home team dominated. Griezmann made his second.
Then it was Carles Pérez’s turn to score his first goal for the Catalans.
Jordi Alba and Arturo Vidal were then accurate. After De Jong lost the ball, Loren Morón made it 5-2.
