The Brazilian player lost his composure, he approached Kerem Akturkoglu and struck very quickly.
The video shows the 25-year-old hitting Akturkoglu with two punches before the pair are stopped by Galatasaray teammates.
Marco received a red card directly after the referee used VAR.
The incident happened in the 61st minute, when Galatasaray was leading by two goals.
After the match, Galatasaray’s coach Fatih Terim said he would issue an internal punishment with Marcao. However, the cause of the crash has not yet been revealed.
Marco joined Galatasaray in 2019 and has been a mainstay in the defense ever since. He made 107 appearances in two years playing for Turkey’s most media-rich team.
This is not the first time two teammates have fought with each other on the pitch.
