What happened: Fabrizio Romano reports that Real Madrid supporters whistled Kylian Mbappe during Wednesday's match at the Santiago Bernabeu. Video circulated by @lejournaldureal captured the jeers, with replies noting Vinicius Junior had drawn similar treatment from sections of the home crowd earlier this season.

Why it matters: The reaction underscores the pressure on Real Madrid's marquee signing as the club's season has yet to deliver a Champions League run that satisfies the Bernabeu faithful. Fan scrutiny around Mbappe has been building for days, and a public whistling inside the Bernabeu raises the stakes for how the club manages its biggest star into the offseason.

What to watch: Watch for Mbappe's next public appearance and any statement from manager or club leadership. Reaction at the next home fixture will indicate whether this was a one-night flashpoint or a sustained shift in crowd sentiment.
