The Brazilian star’s frustration surfaced moments after being withdrawn midway through the second half at the Santiago Bernabéu. Despite Madrid securing a crucial win thanks to goals from Kylian Mbappé and Jude Bellingham, Vinicius’s post-match outburst became the main talking point among fans and pundits alike.

Sources close to the team reported that Vinicius muttered his 13-word message to Alonso near the dugout, suggesting rising tension between the pair. The winger has been substituted several times this season, with Alonso favoring a more disciplined tactical setup.

Vinicius, 25, has contributed five goals and four assists in La Liga so far, yet he has completed the full 90 minutes only three times. His sporadic playing time has raised speculation about whether he remains central to Alonso’s long-term plans.

Alonso, however, chose to downplay the incident after the match. “Vini had a very good performance,” he told reporters. “I don’t want to lose focus on what matters the team’s progress and a deserved victory.”

The manager praised his players for regaining control in high-pressure games, emphasizing teamwork over individual expression. “There are different personalities in every squad,” Alonso added. “We’ll handle these matters internally, as a group.”

Madrid’s victory over Barcelona solidified their position at the top of the table and provided a morale boost ahead of next week’s Champions League trip to Liverpool. However, Vinicius’s reaction has cast a shadow over the otherwise celebratory mood in the capital.

Club insiders say Alonso and his coaching staff plan to speak privately with Vinicius in the coming days to smooth over tensions. The forward’s emotional approach, while often a source of passion on the pitch, has occasionally led to flashpoints with teammates and officials.

Meanwhile, Real Madrid will be without captain Dani Carvajal for several weeks after the right-back was diagnosed with a loose body in his right knee. The Spanish defender is set to undergo arthroscopic surgery and is unlikely to return before January.

Carvajal’s absence could open the door for Trent Alexander-Arnold, who recently recovered from injury, to reclaim a starting role. The English full-back was on the bench against Barcelona and may feature in the upcoming Champions League clash.

As Madrid celebrate a hard-fought win over their fiercest rivals, all eyes now turn to how Alonso manages one of his most mercurial stars. For all of Vinicius Junior’s brilliance, the challenge will be keeping his fire burning without letting it consume the team.
