Video: Mikel San Jose's incredible long range goal against Barcelona

Bilbao players celebrate after Mikel San Jose scores an absolute stunner from halfway line

The first leg of the Supercopa De Espana match between FC Barcelona and Athletic Bilbao ended with a shocking 4-0 defeat for the defending European champions as Luis Enrique’s men were humbled in front of the crowd at San Mames.

Bilbao, who came up as second best in the Copa Del Rey final few months back, stunned the visitors as veteran striker Artiz Aduriz bagged a second-half hat-trick to gain a massive advantage over their La Liga counterparts in the two-legged competition.

Luis Enrique played a gamble in this game by fielding a relatively inexperienced midfield which consisted of Sergi Samper and Rafinha as Iniesta and Rakitic started from the bench for the Blaugranas. Lionel Messi and Luis Suarez lined up in attack while Thomas Vermaelen and Adriano were handed a place in the starting XI ahead of Gerard Pique and Jordi Alba.

The opening 10 minutes were all Barcelona with little or no attacking threat from Bilbao, but they kept pressing the Barcelona players making it hard for the Blaugrana to pass the ball around with any fluency. In the 13th minute, Ander Ter-Stegen found himself running out of the box to make a headed clearance away when he could have just waited for the ball to bounce into his arms.

It was a mistake the German keeper would go on to rue as his header went straight to San Jose in the centre circle. The Basque midfielder controlled the ball with one touch, let it bounce and volleyed it into the net from an unbelievable distance. The raucous San Mames stadium watched along with the players on the pitch in awe as the ball sailed into the net.

It was an absolute stunner that gave Valverde’s side the lead and held on to it until the half time whistle. Barcelona, who looked out of ideas, especially with Bilbao shutting down any possible threats from Messi and Luis Suarez, were further punished in the second half as Los Leones grew in stature. Aduriz scored a hattrick including a penalty to put an end to Barca’s miseries as Bilbao ran out as comfortable 4-0 winners in the end.

With an insurmountable lead, the Basque outfit will travel to Catalonia on August 23 with a hope to claim the trophy at the Camp Nou. And Barcelona have all the odds stacked against them as they will need their talisman Messi and his attacking partners to be at their best to overcome this huge deficit.

Here is the brilliant goal from San Jose.
