AC Milan coach Stefano Pioli has apologised for his outburst towards Manchester United assistant coach Kieran McKenna.
The Italian boss snapped back at McKenna as his side was beaten in the Europa League on Thursday night.
Tensions threatened to boil over following the full-time whistle after a comment made by McKenna, with Pioli also annoyed by his perceived time wasting.
According to Italian media, 34-year-old McKenna told Pioli "good team," with the ex-Fiorentina gaffer taking offence at what he said.
Corriere dello Sport report that Pioli responded: "Good team my a***.
"You are nothing but an a******. Your sister has a good team."
But speaking on Friday to Italian news agency ANSA, Pioli apologised for his words.
He said: "I'm sorry for the reaction I had, it won't happen again. I congratulated Ole Gunnar Solskjaer. I was angry with his assistant."
