Good evening and welcome to Eurosport's LIVE coverage of the Spanish Liga season opener between Athletic Club and Barcelona. We'll bring you all the action as it happens at San Mames. Kick off is at 8pm GMT.

What a win for Athletic Club! And what a way for the match to be decided! There is no doubting who will be on the back pages tomorrow and that will be Aduriz. In his final season for the club, the 38-year-old came on with just minutes left to play and scored an overhead kick to beat the defending champions on opening weekend. Wow.

FULL TIME: Athletic Club 1-0 Barcelona

Tipped over! Barcelona won a freekick high up the pitch, Lenglet got on the end of the delivery and forced Simon into a save. The Athletic goalkeeper tipped the effort over the bar.

I cannot stress enough how incredible a moment that was. That will surely be one of the goals of the season and it came on opening night, in the last minute from a player who had only just come on in his final season for his club, where he is a legend.

There will be three minutes of stoppage time played at the end of the match.

GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Athletic Club 1 (89 mins - Aritz Aduriz) Barcelona 0. INCREDIBLE! What a moment! What a goal! What a way to win a match! The cross came in from the right side, Aduriz lined up the spectacular overhead kick and finds the back of the net! Ter Stegen didn't stand a chance! Wow, wow, wow!

Here comes Aduriz and he replaces Williams for the final few minutes of the match.

All of a sudden, it's as if Athletic Club have realised that they could win this game. They had been sitting back, but now Garitano is waving his players forward. Just a few minutes left of normal time.

Athletic Club wanted a freekick from that last corner kick, but the replay suggests that Berchiche and Rakitic had arms around each other. Not sure what VAR would have said about that.

Header from Griezmann! A corner kick is cleared, but only to the edge of the box. The cross comes back in from Rafinha, but Griezmann's header flashes over the crossbar.

His introduction off the bench was somewhat surprising, but since coming on Rafinha has probably been the best player on the pitch for Barcelona. He's been willing to take a risk.

Another change from Garitano and Benat comes on for the final 10 minutes. Lopez comes off.

Deflected wide! Great play from Rafinha to create the opportunity, weaving through three Athletic defenders, but his strike is deflected wide of the near post. What a goal that would have been.

Time is running out for Barcelona. They are remaining very calm and composed on the ball, but they surely need to start taking some more risks if they are to claim three points here.

The possession from Barcelona is relentless, but they aren't doing much with it in the final third. Athletic Club look pretty comfortable just sitting behind the ball and plugging the gaps.

Indeed, there's the change and it's Roberto who comes off for Perez. Can he make the difference?

It looks like Valverde is going to make his final change and it's Perez who is coming on for the final 15 minutes. That just shows how injuries are affecting Barcelona early on this season.
