Barcelona bolstered their position at the top of La Liga with a hard-fought victory over Athletic Club on Saturday, thanks to a moment of brilliance from Lamine Yamal. However, it wasn't all celebrations for Hansi Flick, who had to address the personal situation of Ferran Torres. The Valencian forward marked his eighth consecutive game without scoring, showing clear signs of frustration before being substituted in the second half.The German strategist remains confident that Torres' speed and dynamism will eventually overcome this poor run of form, despite the striker missing several clear chances during the match in Bilbao. Flick emphasised that the coaching staff is fully committed to helping the player regain his clinical edge, as internal competition for places in the starting XI continues to intensify ahead of their upcoming European fixtures.In the post-match press conference, Flick addressed the Spanish international’s dip in form. "Ferran? He lacks confidence right now, but we are working on it. It’s important to try everything in matches; he’s in a good dynamic, he’s fast, and right now he’s just having a bit of bad luck, but if I can help him, I will," the coach stated. Ferran had a major chance just before half-time with an aerial backheel that missed by millimetres, eventually leading to his substitution for Robert Lewandowski.Lamine Yamal was once again the deciding factor, scoring a trademark left-footed curl in the 68th minute to break the deadlock. Flick also praised the return of Pedri, who came off the bench, and the team spirit, saying: "Of course Pedri changes games; we saw it again today. I am proud of them... this special atmosphere in the team - how they stand together, the environment, everything is fantastic."He added of Yamal: "He didn't have his best game, but his goal decided it. When he has space, opportunities... he trains a lot. It's good that he can solve the game in a situation."
