Juventus coach Massimiliano Allegri was furious at Douglas Costa for “rising to provocation” and being sent off for spitting in the face of a rival, after Cristiano Ronaldo had scored his first goals for Juventus in a 2-1 win over Sassuolo on Sunday.

Both Ronaldo’s goals came in the second half, but the champions’ fourth win in as many games this season was overshadowed by Brazilian Costa’s late red card for spitting at Sassuolo’s Federico Di Francesco — the 24-year-old son of Roma coach Eusebio Di Francesco.
