Kean celebrated scoring Juve’s second goal in the 2-0 victory by spreading his arms when facing the Cagliari fans, having already been subjected to taunts.
Bonucci said after the match that Kean ‘could have done it differently’ and ‘the blame is 50-50’, prompting criticism from Raheem Sterling on Instagram.
Bonucci has since moved to clarify his comments about Kean in a statement on Instagram following Tuesday’s match.
He wrote: ‘After 24 hours I want to clarify my feelings. I was interviewed right at the end of the game, and my words have been clearly misunderstood, probably because I was too hasty in the way I expressed my thoughts.
‘Hours and years wouldn’t be enough to talk about this topic. I firmly condemn all forms of racism and discrimination. The abuses are not acceptable at all and this must not be misunderstood.’
Manchester City star Sterling had branded the idea that Kean was partly to blame as laughable.
‘The blame is 50-50 @bonuccileo19,’ Sterling posted alongside a number of sarcastic laughing and applause emojis.
Also writing on Instagram, Manchester United midfielder Paul Pogba, who used to play for Juventus, said: ‘I support every fight against racism, we’re all equal.
‘Good Italians wake up, you can’t let a small racist group speak for you. #equalgame #respect.’
Kean himself took to Instagram to describe his celebration as ‘the best way to respond to racism’.
