The Italian boss, 47, conceded he had issued a dressing-room paint-peeler after the Blues 3-0 defeat at Arsenal on Saturday.
Conte said: “I was angry but my players were also angry because we weren't satisfied with our performance."
Chelsea have kept just one clean sheet in nine games this season.
And Conte added: “I have to find the solution very soon because I think that we played a very bad game.
“When you have a bad performance, we have a bad performance together — me first, my staff second, then the players."
