Poland striker Robert Lewandowski’s brace earned depleted Barcelona a 2-1 comeback win at Valencia in their first competitive game under new coach Hansi Flick to begin he La Liga season on Saturday.

Barça were dominated by their hosts early in the match and fell behind when Valencia’s Hugo Duro netted a close-range header in the 44th minute.

Thanks to his strikes, the Flick era began with a gritty win against a tough side at a sold-out Mestalla Stadium despite Barcelona missing several key players and featuring three 17-year-olds from the start of the game.

With Ilkay Gundogan, Pedri, Gavi, Ronald Araújo, Frenkie de Jong and Ansu Fati all out with injuries and new signing Dani Olmo yet to be registered with La Liga due to Barca’s breach of Financial Fair Play (FFP) rules, the German manager was forced to be creative in his selection.

Marc Bernal, Lamine Yamal and Pau Cubarsí – all still 17 – were on the starting list in the scorching heat and humidity on the east coast of Spain. Marc Bernal, Lamine Yamal and Pau Cubarsí – all still 17 – were on the starting list in the scorching heat and humidity on the east coast of Spain.

Valencia dominated proceedings early and Rafa Mir was inches from scoring for the locals with two diving headers in the first few minutes, while Cubarsi almost netted two own goals while trying to deflect efforts by Andre Almeida and Diego López.

The visitors hit back quickly, however, scoring either side of half-time through Lewandowski who tapped home Lamine Yamal’s cross deep into added time before the break and fired an unstoppable penalty into the top corner after Raphinha was fouled just after the interval.
