Chelsea manager Antonio Conte has urged his players to remain tight in defence until the final whistle after conceding late on in Tuesday night's 3-1 win at Huddersfield Town.
Tiemoue Bakayoko, Willian and Pedro struck to give the Blues a three-goal lead by the 50th minute of the game, but Laurent Depoitre headed home a 92nd-minute consolation for the Terriers.
Conte was happy with Chelsea's performance as a whole but insisted that clean sheets are crucial for both the goalkeeper and the team, and wants his players to be focused right until the end.
"I think we must be very happy for the performance because from the start of the game we showed a great personality and desire to win the game against a very good team," the Italian told reporters.
"We have to continue in this way to try to play this football. My players enjoyed to play this type of football to have this great combination play between our strikers.
"I saw a lot of positive things, but one negative was to concede at the end and we must improve in this because it is important to keep clean sheets, for the goalkeeper and the team."
Chelsea are back in Premier League action on Saturday when Southampton head to Stamford Bridge.
