BARCELONA: Champions Barcelona suffered a defeat on the opening day of the La Liga season after a sublime winner by Aritz Aduriz handed Athletic Bilbao victory.

Barca produced a lackluster performance and were punished when substitute Aduriz, 38, found the net with a stunning 89th minute scissor-kick.

Luis Suarez and Rafinha both hit the woodwork for Barca but the visitors struggled to impress despite fielding new £107m signing Antoine Griezmann.

Suarez was forced off with an injury.
