The teen has doubled down on his pre-match controversy after joking in an online video stream that Real Madrid "always steals".
Ahead of kickoff at the Santiago Bernabeu, Yamal has followed up that claim by releasing a video on his Instagram account.
Yamal posted an Instagram story celebrating his goal at the Santiago Bernabeu last season. He then uploaded a video in which a voiceover explains the young Catalan's journey: "When he scores, he doesn't celebrate for ego.
"He celebrates because he knows that goal can change everything. For him, for his fans, and for his neighborhood."
The video ends with Yamal saying, "I left my fear behind in Mataró a long time ago."
