Antonio Conte admits that the regularity with which his players are sent off is something that he will need to address if Chelsea are to successfully defend their Premier League title.
The English champions were left reeling a mere 14 minutes into their Premier League campaign when club captain Gary Cahill received his marching orders for a clumsy challenge on Burnley's Steven Defour.
With nine minutes left in the encounter, and his side mounting a spirited fightback, Cesc Fabregas also saw red for committing a second bookable offence.
Speaking to reporters after the match, Conte acknowledged that he will need to look into this worrying trend, referring also to the red cards received by Victor Moses in the 2016/17 FA Cup final and Pedro Rodriguez in last weekend's FA Community Shield encounter against Arsenal.
"We have to pay attention because you can see that in the last three official games, we finished twice with 10 men against Arsenal and today with nine men," he said.
"Also me, I have to study a new formation with 10 players online, because when it happens with this regularity you must be worried."
Conte was diplomatic when asked about his opinion off referee Craig Pawson's decision to show Cahill a straight red, but hinted that he felt that it may have been too harsh a punishment.
"I prefer not to comment on the referee's decisions. I think that the coach can make mistakes, the players can make mistakes, the referee [too]," the Italian said.
"For sure it was a key moment, because after this red card we lost our composure and we conceded three goals," he continued.
"We have to improve a lot on this aspect because a situation of this type can happen, but we must pay attention to try to think that there is the rest of the game to try and do our best," Conte added.
