I disagree. He is his coach, he needs to make sure his player keeps his head on the pitch. Of course, he highlight to him if he thinks Kean reacted wrongly. I concur that it would have been better to do that in private, to avoid linking the two together. But is wrong to group Allegri, who clearly came out against the racist and explicitly said that nothing (e.g. Kean's celebration) justifies their behavior, together with Bonucci. That was the original comment I reacted, too, and that context is getting lost a bit here.
