Barcelona striker Antoine Griezmann was left floored after their Supercopa de Espana final defeat to Athletic Bilbao.

Barca lost 3-2 in extra time after Inaki Williams hit a stunning late, late winner.

While disappointed after the loss, Griezmann urged fans to be positive, insisting they're still alive in three competitions - LaLiga, Champions League and Copa del Rey.

Jordi Alba, meanwhile, admits Barca paid for a poor first-half, with both players agreeing that Athletic Club made the most of the mistakes made.
