Chelsea boss Mauricio Pochettino admitted relief after their late win at Crystal Palace.
Chelsea won 3-1 with two goals struck by Conor Gallagher and Enzo Fernandez in injury-time.
Pochettino said: “We saw two different sides. In the first half we were so flat and I was so disappointed. In the second half much better and I am very pleased with how we finished the game. We deserved the three points.
“The energy wasn't the right energy and the intensity we showed was not great. We dominated but we played so slowly and they way we conceded, we cannot allow to give this type of option to the opponent.
“It is a massive win. That is our challenge to be consistent but this type of fixture will help us build our confidence."
He also stated: "We started the second half really well and we scored. It was a tough game but I'm so pleased.
"We just want to build our confidence and realise we need to be more consistent. We used two strikers in between the centre back and the full back. We put Gusto and Chilwell higher and moved the ball quicker with Enzo in a number 10 role. It helped us score."
