Ante Budimir scored twice to help Osasuna earn a shock 4-2 home win over leaders Barcelona and hand the visitors their first defeat of the LaLiga season on Saturday.
Bryan Zaragoza, on-loan from Bayern Munich, crossed to Budimir to open the scoring with a close-range header in the 18th minute and the 23-year-old winger extended Osasuna's lead with a strike from a quick counter-attack 10 minutes later.
Barca reduced the deficit thanks to a massive blunder by Osasuna goalkeeper Sergio Herrera who failed to keep out a weak strike by Pau Victor in the 53rd minute, but Budimir extended the hosts' lead from the penalty spot in the 72nd minute, after he was fouled inside the box.
