Milan have apologised to Inter for Gennaro Gattuso's decision to sing along with fans in an anti-Leonardo chant.
The midfielder took part in the derogatory chant about the former Rossoneri boss during the Scudetto celebrations at the Stadio Olimpico on Saturday night.
"As a club, I say sorry to Inter, President Massimo Moratti and Leonardo, a man I love as a friend," Milan Vice-President Adriano Galliani said.
The apology came after Galliani met with the Italian midfielder at the club's headquarters on Thursday afternoon.
Milan have apologised to Inter for Gennaro Gattuso's decision to sing along with fans in an anti-Leonardo chant.
The midfielder took part in the derogatory chant about the former Rossoneri boss during the Scudetto celebrations at the Stadio Olimpico on Saturday night.
"As a club, I say sorry to Inter, President Massimo Moratti and Leonardo, a man I love as a friend," Milan Vice-President Adriano Galliani said.
The apology came after Galliani met with the Italian midfielder at the club's headquarters on Thursday afternoon.
"I gave Rino a shampoo," the official added. "He knows what I said to him, but I don't like to reveal private matters with others.
"Nevertheless, I told Gattuso that he made a mistake so let us now forget about this whole incident."
Leonardo was so offended by the abusive chant that he released a statement on the Nerazzurri's official website.
Moratti too also criticised the 2006 World Cup winner.
Gattuso and Leonardo had a difficult relationship last term while the Brazilian was in charge of the Milan side. He left at the end of the season and joined Inter in December.
