The Italian was extremely frustrated and disappointed in the wake of Friday night's 2-1 home defeat to Liverpool in the Premier League.
Conte blamed his players for losing concentration and not paying attention, particularly for Liverpool's opening goal scored by Dejan Lovren, and has implored them to quickly improve in Tuesday night's EFL Cup third round fixture against Leicester City at the King Power Stadium.
Asked of his message to the players, Conte told Chelsea TV: "The same message that I gave after the game, that when you concede two goals in this way – after a free-kick and throw-in – we must pay attention in every moment of the game.
"You must pay attention to details because details change results. In this case it happened because when you are losing 2-0 it's very difficult to win or draw.
"The reaction was good, we scored a goal and we could have scored another but it was late."
