Champions Juventus took a huge step towards retaining the Serie A title by beating second-placed Napoli, with both sides reduced to 10 men.
Napoli goalkeeper Alex Meret was given a straight red card for tripping Cristiano Ronaldo and Miralem Pjanic curled in the resulting free-kick.
Emre Can headed a second, before Pjanic was dismissed for deliberate handball.
Jose Callejon pulled a goal back and Napoli’s Lorenzo Insigne missed a late penalty.
The spot-kick was awarded by the VAR six minutes from time after Fabian Ruiz‘s cutback hit Alex Sandro on the arm, although the Juventus defender knew little about it.
Referee Gianluca Rocchi jogged over to have a look at the replay on the pitchside monitor and awarded the penalty, but Insigne rattled the post.
Juve have won the title for the last seven seasons and now hold a 16-point advantage with 12 games remaining.
