Antonio Conte has admitted that he is "not happy" with Alvaro Morata after the striker was shown yellow cards for diving and dissent in Chelsea's win over Norwich City on Wednesday night.
The Blues were given a real scare by the Championship outfit in the FA Cup third-round replay, having been taken to extra time and penalties at Stamford Bridge.
Chelsea were made to play the final stages of the contest with nine men, as Pedro and Morata were dismissed by referee Graham Scott for two bookable offences each.
Both players received a caution for diving, and Conte admitted after the 5-3 penalty-shootout win that his players should not attempt to con opposition sides.
"The first yellow card [for Pedro] was for a doubtful situation – I didn't watch Morata's situation yet – but the second was for dissent," he said.
"You must pay great attention. In this moment of the game, you have to pay great attention to stay calm and make the best decision. I don't want an advantage.
"About Pedro, if there is a dive, it's right to take a yellow card. It's the same for Morata. I don't want an advantage, especially if you know this system (VAR) is being used.
"You can watch every situation with this technology. If someone gives a punch or an elbow, you must pay great attention. In this case, if it wasn't a penalty, it was right to give a yellow card. For sure, I'm not happy for the second yellow card for Morata."
Chelsea will now face Newcastle United at home in the fourth round of the competition.
