Antonio Conte has insisted that Alvaro Morata will overcome his disciplinary issues and has blamed his sending-off against Norwich City on the pressure of being Chelsea's first-choice striker.
The 25-year-old was shown two yellows in the space of a few seconds during the latter stages of extra time in Wednesday night's FA Cup third-round replay.
Morata's first caution was for a perceived dive, while the second was for dissent towards referee Graham Scott as he felt the decision was incorrect.
Conte agrees that it was wrong for the Spaniard to be booked for the dive, but says that it is important lessons are learned from the incident.
"For the strikers, this situation can happen," he told reporters at his weekly press conference. "For Alvaro, this is the first season that he's been having a full season. Maybe, for him, this is the first time to face this type of problem. But he has to overcome this problem because this is a stupid problem.
"You have to work for the team and not lose confidence. The coach trusts him, his team-mates trust him, the club trusts him, the fans trust him. I don't see a problem, but this is the first time Morata has faced this situation. Before, if you stay on the bench, you don't have this type of pressure. So now he has to learn to face this type of situation, move forward and go on.
"I think the player knows very well his mistake. There was frustration for the first yellow card, because the player didn't deserve it. If the referee doesn't want to give the penalty, in this situation it's still not right to book him.
"But, at the same time, you must learn to control yourself. The second yellow card was for dissent. I agree with the player for the first yellow card, but I don't agree with the player for the second yellow card. He has to check himself in future."
Chelsea, who also lost Willian to a red card, will now face Newcastle United in round four after beating Norwich on penalties.
