"I said I'll help Athletic Bilbao until the last day"

Aritz Aduriz said he will always be available to help Athletic Bilbao until the last day after his stunning bicycle kick downed Barcelona 1-0 in the LaLiga opener.

Aduriz plans to retire at season's end but the 38-year-old Bilbao star showed he still has plenty of football left in the tank thanks to his unforgettable 89th-minute winner on Friday.

The club great scored within a minute of his introduction via a spectacular overhead kick against the LaLiga champions at San Mames.

Aduriz's goal saw him match a Lionel Messi scoring feat, having now scored in 15 consecutive seasons in Spain's top flight, and the veteran striker revelled in the result.
