Manchester City boss Pep Guardiola was tightlipped on his row with Darwin Nunez at the end of their 1-1 draw with Liverpool.
They shook hands before things escalated as words were exchanged.
Reds manager Jurgen Klopp had to drag away Nunez from an angry row with Guardiola at the final whistle.
Asked what happened at his post-match presser, the Spaniard simply said: "Nothing."
Guardiola then walked out of the press conference before any more questions could be asked.
