Sean Dyche wants his players to find the freedom to play, after Burnley suffered a fourth straight Premier League defeat.
First half goals from Jorginho and Tammy Abraham made it another tough day at the office for the Clarets, who were earlier denied an opener from Jeff Hendrick by the tightest of VAR offside decisions.
Callum Hudson-Odoi then killed off any hopes of a fightback early in the second half.
Dyche, who could only name five defenders on the bench at Stamford Bridge, said: “We have had injuries and illness and it’s not ideal, but I still expect a lot from my players and I thought the starting 11 we put out today could compete.
“We’re in a tough period at the minute and we just need to free the group up a bit.
“Nobody is quite playing with that fluidity and anticipating the game. That’s from tightness and not getting results and it’s not easy.
“We have to come out of that because it’s a vicious circle.
“You have to free yourself up and be confident enough to go and win a game, but equally you could argue that wins bring that confidence.
“It’s the chicken and egg scenario and this is the reality of the Premier League.
“We’ve been in this league long enough to know that we can have spells like this. It’s now about coming out of this spell and we’ve done that historically.
“We will have to do it again and we are in a much better position than we were last season.
“We have a healthy points total, but we’re having a tough period. It’s very rare when you are Burnley that you don’t have that.”
Dyche, who revealed absent striker Ashley Barnes will see a second specialist on Monday to reveal the extent of his troublesome groin injury, admitted: “Chelsea were too strong overall.
“We came here to try and keep things tight early in the game and did that pretty well, before we gave away a penalty.
“I’m a little aggrieved by the second goal because Tarky has two arms in his back from their centre forward, who then scores.
“Popey should inevitably save it, and he will be disappointed with that, but at the end of the day that’s a foul.
"Unfortunately though, we are having a run of making mistakes at the moment and getting punished for them.
“We have to eradicate them, to be sure. You definitely can’t give soft goals to teams like this.”
