Juventus-Napoli refereeing analysis: Should Koopmeiners have seen red? Marelli: “High contact, but the foot slips quickly.” Woltemade and Cabal appeal for a penalty. Marianucci sent off

Juventus v Napoli Sunday at 20.45

SOZZA

IMPERIALE - COLAROSSI

IV:     DOVERI

VAR:     MERAVIGLIA

AVAR:       GARIGLIO

Marianucci goes in late and clearly steps on Cabal's foot. Sozza shows him a second yellow card and sends him off.

Juventus go direct again. Koopmeiners reaches the byline and crosses into the centre of the box, where Woltemade goes down after contact with Olivera: "I agree with Giaccherini, there’s very little in it. An arm is placed on him, but there’s no holding. Not enough to award a penalty."

Shortly after Cabal accidentally hits the post, the defender chases the ball. Olivera, watching the ball rather than Cabal, accidentally steps on the back of his boot and brings him down. Sozza lets play continue, and the VAR check confirms the on-field decision.

Marelli: "It resembles the contact on Da Cunha in Torino-Como, with one difference. The Como midfielder was caught square on the ankle; in this case, Cabal was only clipped, and I agree with VAR's decision not to intervene over contact that was not decisive."

Lucumì catches Lucca with his knee at neck height in another borderline challenge. Sozza gives the foul but does not show a second card, judging the contact to be genuine in the course of play.

This time, Lucumì deserves the yellow card for stopping Lucca on the counter-attack. A textbook booking.

Sozza takes no action over the incident involving Koopmeiners, then shows Douglas Luiz the match's first yellow card for a challenge on Rafa Marin. It's a foul, but an honest attempt to win the ball. A harsh booking.

Refereeing analyst Luca Marelli said: "From the image we’ve seen, Koopmeiners should have received a yellow card. The contact is very high on the calf, midway between the calf and the ankle. Let’s see what they say on VAR, although serious foul play is a possibility. The point of contact is very high, but I want to make one crucial point: the right foot slides off the ankle, so it does not meet the threshold for a red card."

Frank Anguissa takes a huge risk as the last man. He fails to spot Koopmeiners pressing high up the pitch and catches him before the ball as he tries to tackle. The ball goes out of play. The replay shows a clear foul, with the Dutchman's initial point of contact very high. Sozza makes no decision and VAR does not intervene.

Napoli protest to Sozza after McKennie's challenge stops De Bruyne's break towards Vicario's goal. The referee lets play continue and takes no action, though McKennie had taken a big risk.
