Leonardo Bonucci has backtracked on suggestions his Juventus team-mate Moise Kean was partly responsible for the racist abuse he received from Cagliari supporters by insisting he was "misunderstood".

The defender had said Kean "could have done it differently" and "the blame is 50-50", after the 19-year-old spread his arms while facing the crowd after scoring.

Bonucci had since been criticised by, among others, Raheem Sterling for saying so, but now says he was "too hasty".

There was further support from Eni Aluko, who plays for Juventus Women and who wrote on Twitter: "I choose to support my Juve counterpart not blame him. The good news is the ignorant idiots of Cagliari are going absolutely nowhere in life, whilst Kean is a rising superstar and Matuidi a World Cup winner. I also focus on that. Kean 1 Racist Cagliari idiots 0."

Kean posted a message on Instagram with a photo of his celebration and a caption which read: "The best way to respond to racism #notoracism."

Former Wigan striker Jason Roberts, now CONCACAF director of development, applauded the players who are standing up to racism but questioned why it should fall to them to do so.

Roberts told the conference: "I think it's deeply troubling when you see a young player having to endure what was thrown at him, and that we have to watch somebody at 19 years old put in a position of leadership like that.

"What was stark was the reaction of some opposition players and some of his own players to move him away from the situation as if he had done something wrong. I think he showed remarkable maturity to not react more. Who else in the workplace would have to endure what that poor young man had to go through?

"We are seeing the rise of it in society and again in football. This is about representation, about the toughest of sanctions ensuring players have the confidence in the governing bodies and decision-makers that the sanctions match the crime.

"I'm not sure we have that at the moment and that's why we have a climate where managers, players, both black and white, are saying that they will walk off the pitch.

"If that happens it leaves us in a very difficult position. It means we are not doing enough and that the players are being asked to lead on this issue again."

Anti-discrimination campaigners Kick It Out condemned the Italian federation as well as Allegri and Bonucci, saying: "This is the third year in a row that black players have been racially abused at Cagliari...and yet the Italian FA allows it to continue."
