Barcelona secured their second consecutive La Liga victory with a 2-1 win over Athletic Bilbao, thanks to goals from teenager Lamine Yamal and veteran striker Robert Lewandowski. Yamal opened the scoring with a deflected shot in the 24th minute, but Bilbao equalized just before halftime through Oihan Sancet's penalty. Lewandowski, who had missed several chances, netted the winner in the 75th minute from a rebound, maintaining his prolific scoring form. Under new manager Hansi Flick, Barcelona shares the top of the table with Celta Vigo, both teams having six points from two matches. Athletic Bilbao, now with one point from two games, continues its winless streak at Barcelona, dating back 23 years. Lewandowski's late goal solidifies his role as a crucial player for the team, having scored in both matches this season.
