Carlo Ancelotti is a firm believer in the practice of shaking hands with opposing managers. Arsenal boss Arsene Wenger stormed down the tunnel following his side's 3-0 defeat in the Carling Cup at the City of Manchester Stadium.
Hughes labelled Wenger "ungracious" and other Premier League managers weighed in with criticism.
"I think that shaking hands is a normal thing," Ancelotti said.
"Mark Hughes is a very good coach. I know him. For me, it's not a problem to shake hands. You show respect to the other coach. It's normal.
"In Italy, it's not usual to do that at the end, immediately after the game.
"In England we have to do it. I think it's a good thing to maintain calm and the atmosphere.
"I don't know why Wenger didn't shake hands with the other coach. I don't know if it was right or wrong. Every person can do what he wants to do."
