Juventus coach Max Allegri defended Moise Kean after his goalscoring performance in victory over Cagliari.

Allegri was asked about goalscorer Kean, who was subjected to racist jeers after his celebration in front of the fans with arms outstretched.

“He scored another goal and did better in the second half, whereas he got more or less everything wrong in the first half," replied Allegri after the 2-0 win.

“I didn't hear anything from the stands, as I was focused on the game. You need great intelligence to deal with these situations and should not go to provoke people. That, of course, does not mean the idiots in the crowd and the way they reacted should be justified.

“As always in life, there are idiots who do stupid things and ruin it for everyone else. I don't think talking about it all the time helps. I don't think halting play helps, because not everyone in the stadium did that.

“We need to use the cameras, find those who are doing it and punish them. It's very simple, identify them and not one-year ban or two, just give them a lifetime ban. We've got the technology, it can be done if the authorities want to. The problem is, they don't really want to."
