VAR continued to be trialed in England during Wednesday's Carabao Cup semi-final first leg at Stamford Bridge, with the system used on numerous occasions, including a penalty appeal from Chelsea in the closing stages, with Danny Welbeck's tackle on Cesc Fabregas rightly being ruled as a fair challenge.
For Conte, though, the five minutes of injury time added on at the end of the second half was not comparable to the amount of stoppages caused by reviewing video evidence.
"For me, there's disappointment about [not enough] extra time," Conte told Sky Sports.
"In the second half the doctor went onto the pitch twice and the referee stopped for VAR, so you have to give more minutes of extra time.
"In Italy sometimes extra time can be seven, eight or nine minutes."
