By Ben Morse, CNNUpdated 1106 GMT (1906 HKT) August 22, 2022 Robert Lewandowski celebrates scoring Barcelona's third goal against Real Sociedad.(CNN)Robert Lewandowski and his new Barcelona teammates showed how dangerous they might be this season with a thumping 4-1 victory over Real Sociedad on Sunday, but it wasn't without controversy.
Lewandowski, signed from Bayern Munich this summer, scored his first Barça goal in the opening minute of the game, only for Alexander Isak to equalize five minutes later.
With the scores level, France international Ousmane Dembélé appeared to catch Sociedad defender Aihen Muñoz in the face with his elbow.
Dembélé avoided a red card and, in a cruel twist of fate, scored Barcelona's second goal of the game after a sumptuous backheel assist from substitute Ansu Fati.
