Flick started with a win over Valencia thanks to a brace from Lewandowski

Hans-Dieter Flick made his debut as the head coach of FC Barcelona. The German coach's first official match was successful in terms of result, as his team defeated Valencia away from home.

In Barcelona's starting lineup, three 17-year-olds—Kubarsi, Casado, and Yamal—took to the field. The teams exchanged goals toward the end of the first half. The hosts took the lead through Duro, but a few minutes later, Lewandowski, assisted by Yamal, equalized the score.

At the start of the second half, Lewandowski converted a penalty to beat Mamardashvili and put the Catalans ahead. This goal turned out to be the winner for the visitors, allowing them to secure three points in the season opener. Notably, Robert Lewandowski has scored in three consecutive official matches for Barcelona.

Valencia — Barcelona — 1:2
Goals: Duro 44' — Lewandowski 45+5', 48' (penalty).
