Luciano Spalletti defended the performance of referee Gianluca Rocchi in Inter's exhilarating 2-2 draw at Roma, but Francesto Totti was left frustrated by what he saw as "shameful" officiating.
The Nerazzurri were twice pegged back in Sunday's Serie A encounter, with Cengiz Under's stunning strike and an Aleksandar Kolarov penalty cancelling out Keita Balde Diao's effort and Mauro Icardi's thumping header.
Roma were incensed in the first half when Rocchi opted not to award a spot-kick for an apparent Danilo D'Ambrosio trip on Nicolo Zaniolo, with Roma legend Francesco Totti questioning why VAR did not spot the offence when discussing the incident after the game.
“Everyone saw it, there’s no need to describe. I want to know, and we all do, how those in the VAR booth didn’t see that foul. We all saw it on a far smaller screen. It’s shameful," Totti said.
“Why don’t you call them and ask how they didn’t see that? This is precisely what VAR was introduced for. Rocchi might’ve seen it or not, but that’s not the issue. The VAR officials had to see it. Fabbri was watching another game on his screen, evidently.
“We cannot go on like this. There are meetings, we go here and there to discuss how VAR is used, when and in what way, then it’s not used on an incident like this?
“That’s not because it’s Roma, it could happen to any club. It’s impossible. Someone ought to call Fabbri and ask: ‘What were you looking at?’ It’s all fine to laugh and joke, but this is serious.
“We’re not seeking alibis, but this changes the game. We could’ve taken the lead, moments later Inter score. It changes the entire match and that can change an entire season.”
But Spalletti, who was dismissed late on for dissent, believes the official had a good game.
Speaking to Sky Sport Italia, he said: "We were told that if there is a 50-50 situation, it should be viewed.
"But then people complain there are too many incidents and then it drags the game on too much.
"I thought Rocchi made a lot of good decisions, including the one to send me off, as I over-reacted on the touchline.
"It was an exciting counter-attack, he interrupted it and I lost my temper. It's fair."
Inter's draw means they head into Friday's Derby d'Italia at Juventus 11 points adrift of the Serie A leaders, while Roma are seventh amid growing pressure on boss Eusebio Di Francesco.
But Spalletti feels a point each suited all parties.
"It was a very entertaining match for all watching and I think a valuable point for both teams," he added.
"It shows we are on the right track and what we need to improve on."
