Real Madrid forward Vinicius Jr has apologised to the fanbase for his reaction when replaced in the recent fiery Clasico clash triumph.
The Brazilian was replaced in the 72nd min and displayed his disappointment by heading directly off the pitch.
Vinicius later returned to the sidelines and, after his team's narrow triumph, sought to engage the opposition's Lamine Yamal during unpleasant post-match incidents.
"Today I want to express regret to all the supporters for my reaction when I was taken off in the Clasico," he posted on his account.
"Similarly to I have said in person during today's session, I would like to express regret anew to my teammates, the club, and the leadership.
"At times emotion gets the better of me because I always want to triumph and support my team. My winning mentality stems from the passion I have for this team and everything it stands for."
The player joined Real from Flamengo in the year 2018 for £38.7m and has notched 111 goals in 335 appearances.
But his career in the La Liga is far from certain with rumors in recent months stating that the club would think about allowing the 25-year-old move on if they were to receive a appropriate bid.
When Vinicius was substituted on the match day, cameras from broadcaster the service recorded him remarking: "It's always me! I'm leaving the team! It's better if I depart, I'm leaving."
In his latest message on social media, Vinicius stated: "I vow to keep battling at all times for the benefit of Real Madrid, as I have performed since the first day."
