Guus Hiddink feels Chelsea seriously required a victory from their trip to Crystal Palace on Sunday.
The Dutchman guided the Blues to their first win under his interim reign with a confident performance in the 3-0 victory at Selhurst Park which came courtesy of goals from Oscar, Willian and Diego Costa.
Following draws with Watford and Manchester United, Chelsea were in desperate need of a win and Hiddink was delighted to see his players deliver.
"It was a very important step today, because we were playing after two draws and you could see the team desperately needed a win," Hiddink told Sky Sports.
"We have played well, but have been a bit unlucky conceding goals, but we needed this win. It's a good step forward, it's the way Chelsea should be, and the way of playing today was very acceptable.
"You get confidence by playing, and these are quality players. [But] quality is not enough, they must know that you must sacrifice and be well organised defensively. I don't mean dropping back, but defending well in your own area. From there, you can use your quality."
He added: "It's normal and not that long [since], but after a beautiful championship, you have a tendency to be a bit complacent.
"We come from almost the bottom and it's very hard to achieve what we want to achieve, but giving what we did today, it gives a lot of confidence."
