Real Madrid defender, Antonio Rudiger, slapped younger teammate Alvaro Carreras during a dressing room row.
It is claimed that both players had to be pulled apart during the incident at the training ground.
Rudiger “lost his mind” following their 1-1 draw with Real Betis two weeks ago.
In a statement, Carreras confirmed the clash and insisted the matter has been resolved.
The 23-year-old said: “Regarding the incident with a teammate, it was an isolated matter without importance that has already been resolved. My relationship with the entire team is very good.”
Rudiger is believed to have apologised to Carreras and taken the players out for dinner with their families last Friday.
