VIDEO: Adruiz scores beautiful header to give Athletic Bilbao 1st half lead

Athletic Bilbao's encouraging play over the last month continued Saturday against league-leaders Real Madrid.

Bilbao got the home fans on their feet inside the first half hour when Aritz Aduriz connected with Mikel Rico's curling cross into the box and thumped a header past Iker Casillas.

To Casillas' credit, it was virtually unstoppable as the ball was placed perfectly into the top corner and curled around the Madrid 'keeper's outstretched hand.

Bilbao have a chance to extend their unbeaten streak to six matches if they can hold off Real Madrid.
