Several incidents came under the spotlight at Stamford Bridge in midweek, where the Blues had multiple penalty appeals waved away by referee Graham Scott while Pedro, Alvaro Morata and Willian were all booked for diving.
It remains unclear whether the match official employed VAR to aid any of his decisions, and speaking after the game, Conte admitted he was frustrated by the decisions, especially the one not to award Willian a penalty.
"I think that we need to improve if we want to use this new system," Conte said. "Today [Wednesday] in this game there is a very clear situation with Willian. I think the situation was very clear and I watched and it's a penalty, very clear.
"The referee quickly took a decision to book Willian. It means you don't have doubt. If we want to improve this new system you have to wait to check with the person that is watching the game and then if this person is sure, 100 per cent, then OK it's simulation book him."
He added: "To avoid a big mistake you have to call the referee and tell him: 'maybe this situation, there is a doubt, for me it's no penalty but it's better you go watch and then make the decision'. We have to respect the referee on the pitch and he has to make the final decision, not another person saying they are 100 per cent sure and don't call the referee. The referee watches and then makes the best decision."
