The winger was sent off in the closing stages of Juventus' Serie A win over Sassuolo but his manager refused to make excuses
Juventus head coach Massimiliano Allegri has condemned Douglas Costa's violent outbursts that led to the Brazilian being sent off in a 2-1 win over Sassuolo.
Costa elbowed, headbutted and spat in the face of Federico Di Francesco in the closing stages of a game in which Cristiano Ronaldo scored twice to give Juventus the lead.
The winger could be slapped with a three-match ban that would include Juventus' clash with Serie A title rivals Napoli on September 29.
