Antonio Conte criticised Alvaro Morata for getting himself sent off during Chelsea’s FA Cup clash with Norwich.
Chelsea prevailed on penalties at Stamford Bridge, where Morata and Pedro were dismissed towards the end of extra time.
Having been booked for diving after going down in the penalty area under a challenge from Christoph Zimmermann, Morata’s reaction immediately brought a second yellow card, for dissent.
Blues boss Conte said: “For sure I am not happy for the second yellow card to Morata.
“The first was for a doubtful situation, but the second was for dissent. You must pay great attention because in this moment in the game you have to stay calm.”
Morata must now serve a ban, limiting Conte’s attacking options for Saturday’s away game against Brighton.
“We have to play in two days against Brighton and we have to try to recover very well,” said Conte.
“It will not be easy. We face many problems and after the red cards Pedro and Morata are not available.”
