Massimiliano Allegri passionately supported referee Daniele Chiffi's decision to award Filip Kostic's controversial winner after Juventus beat Inter 1-0 on Sunday.

Kostic drilled home brilliantly to give Juve the advantage after 23 minutes at San Siro but a lengthy VAR review followed to ascertain whether the ball had hit Adrien Rabiot's arm in the build-up.

However, the goal stood and Allegri's men would not relinquish that lead as Juve triumphed for the sixth time in their last seven Serie A games to move within seven points of the Champions League places.

When questioned on the decision to allow the goal, Allegri was quick to back Chiffi and the VAR's decision to stay with the original verdict.

"Don't make me angry," the Juve head coach told DAZN after the match. "The referee's decisions must be accepted. The decisions go one way or another.

"Let's not make a lot of noise, it wasn't easy for Chiffi to referee. Let's talk about football, not referees.

"I said if VAR is objective, then it is functional, but if it becomes subjective, that is a problem. This tonight is an objective case, we have not made any controversy.

"The less we talk about referees, the more we help them."

Juve completed the double over Inter while keeping a clean sheet in both games for the first time since the 1976-77 campaign, yet Allegri wants his side to be more ruthless going forward.

Speaking at his post-match press conference, the Italian said: "The boys trained well for this. It was a good game, winning in Milan isn't easy and it raises our confidence.

"We had a good match from a technical point of view, we conceded little against a strong and technical team.

"In the second half, however, we had to close it."

Allegri went down the tunnel before the final whistle, missing a fiery ending that saw Danilo D'Ambrosio and Leandro Paredes dismissed after the final whistle for their roles in a post-match confrontation.

Asked why he decided to make an early exit, Allegri told DAZN: "They didn't need me any more at that point.

"I was getting irritated, so rather than get myself booked or sent off, I decided it was best to leave. I left it in their hands, the players knew what they were doing."
