An Antoine Griezmann double allowed Barcelona to return to winning ways with an emphatic 5-2 La Liga win over Real Betis on Sunday. After the champions were surprisingly beaten 1-0 by Athletic Bilbao in their opening match of the season last week, they rebounded in style on Sunday. Strikes from Carles Perez, Jordi Alba and Arturo Vidal completed a memorable day for the Catalans as they marked defender Gerard Pique's 500th appearance for the club.
