Robert Lewandowski and Lamine Yamal's second-half strikes earned Barcelona a 2-0 win over Osasuna on Thursday and set up a Spanish Super Cup final Clasico rematch. The Catalans beat Real Madrid in last year's final and will face their bitter rivals again Sunday after Los Blancos beat Atletico Madrid in an eight-goal thriller in the first semi-final in Saudi Arabia. "We want to take the ball off Madrid, that's our DNA, we're hugely motivated, it's the moment to show our best football," Xavi told reporters. "We're in another final, another Clasico, which was our main objective -- we didn't play a brilliant game, but a serious, sensible one." Osasuna goalkeeper Sergio Herrera kept Barcelona at bay before Ilkay Gundogan slipped in veteran forward Lewandowski to open the scoring before the hour mark.
