Athletic Bilbao hat-trick hero Aritz Aduriz has admitted that it his "almost impossible" for Barcelona to recover from their 4-0 first-leg defeat in the Spanish Super Cup.
Aduriz starred as Bilbao stunned Luis Enrique's side at San Mames last night with a result that puts them on the brink of their first trophy since 1984.
However, the 34-year-old is refusing to rule out the treble-winning Catalans ahead of Monday's return leg at Camp Nou.
"We cannot think that four goals are sufficient. They are the best and are capable of anything," he told reporters.
"We are very satisfied. Barca scoring four goals is almost impossible, but [the second leg] is back [in Barcelona] and will be very hard."
Mikel San Jose opened the scoring for the hosts.
