Kean, 19, spread his arms while facing the crowd after scoring Juve's second goal in Tuesday's Serie A win.

Bonucci said Kean "could have done it differently" and "the blame is 50-50".

England international Sterling, 24, said: "All you can do now is laugh."

Italy defender Bonucci, 31, responded by writing: "Regardless of everything, in any case... NO TO RACISM."

Racist chanting was directed at several England players during their 5-1 Euro 2020 qualifying win over Montenegro in Podgorica last month.

Sterling gestured to the crowd by putting his hands to his ears after scoring, and later called on football's authorities to take "a proper stance" against racist abuse.

Following the game, Bonucci told Sky Sport Italia: "Kean knows that when he scores a goal, he has to focus on celebrating with his team-mates. He knows he could've done something differently too.

"There were racist jeers after the goal. Blaise (Matuidi) heard it and was angered. I think the blame is 50-50, because Moise shouldn't have done that and the Curva (fans) should not have reacted that way.

"We are professionals. We have to set the example and not provoke anyone."

Leonardo Bonucci responded with this post following criticism of his comments

Juventus boss Massimiliano Allegri said Kean "shouldn't have celebrated in that manner" but called on the authorities to act.

Italy and Juventus captain Giorgio Chiellini defended Kean's actions, saying he had watched the incident again after the match and concluded his young team-mate "did nothing".

"Moise is a legacy of Italian football, a golden boy, who is doing his best and should not have to pretend for what he is not," Chiellini, 34, said.

Kean posted a picture of his celebration on Instagram after the game with the caption: "The best way to respond to racism."

Kean's agent, Mino Raiola, told BBC Sport that anyone at Juventus not willing to fight racism should leave the club.

"Nobody should justify racism in any way or form," he said. "Racism is equal as ignorance. There is no excuse for it. Federation, clubs and players should draw one line.

"A country like Italy should be leading on this given how many millions of Italians live abroad. You cannot be racist and Italian. You cannot be human and racist."

'What happened to Kean is inexcusable'

Bonucci saying Kean had to take a share of the blame was the "worst scenario" for a player who had suffered racist abuse, according to former Manchester City midfielder Yaya Toure.

The 35-year-old Ivorian said he would have challenged Bonucci over the comments if he was Kean and that Bonucci should apologise.

"Having your team-mate attacking and saying things like that is unbelievable. It was totally disrespectful," Toure said.

"When this kind of situation happens people of course look to the black players but I feel Bonucci needs to be a bit cleverer and smarter than that."
