Mario Lemina had dominated the headlines heading into Tuesday night’s encounter between Galatasaray and Barcelona in the Champions League.

Ahead of the match, the Galatasaray midfielder raised eyebrows when old comments of his resurfaced on social media, in which he appeared to dismiss Lamine Yamal in favour of his teammate Leroy Sane.

As it turned out, the Gabon international picked the worst possible opponent to provoke, as Lamine Yamal did the talking with his football.

Indeed, Yamal ran the show in Barcelona’s 4-1 win in Istanbul, collecting the Player of the Match award after an exhibition that included a stunning fake-rabona assist for Anthony Gordon’s goal.

The teenager then took to social media with a pointed message of his own, posting a carousel of images from the game alongside the caption, “Do you know me now?” , accompanied by a ghost emoji.

Faced with that response, Lemina appears to have waved the white flag.

The 33-year-old softened his stance entirely, sharing an Instagram story featuring a photograph of his young son posing with the Barcelona star.
