Italian Football Federation observers reported hearing Koulibaly targeted by the chanting in the game on September 29 which hosts Juventus won 3-1 to move six points clear of Carlo Ancelotti’s side.

As a result, the ‘Curva Sud’ will be closed for one game — against Genoa on October 20 — when the champions push to keep their 100% record with a ninth win in the league this season.

“I don’t believe that the club should bear the responsibility for racist chants that none of us like to see or hear,” said Juventus lawyer Luigi Chiappero.

“There’s an obvious disparity of treatment between Juventus and other clubs.

“It is time to apply individual responsibility, at least where technology allows it, as in the case of Allianz Stadium.”

The Italian FA also fined the club 10,000 euros (US$11,500).
