Liverpool manager Brendan Rodgers says referee Anthony Taylor should have given his side a penalty when Steven Gerrard's shot hit Gary Cahill's arm late in the game against Chelsea.
The Reds suffered their fifth defeat of the season as their negative start to the season continues.
"We worked so hard in the game but we need those decisions that are obvious, it was a clear, clear penalty," Rodgers told BT Sport.
"I was very disappointed because the players gave everything in the game. We deserved at least a point for sure.
"You need that wee bit of luck going for you and it isn't at the moment. It has been a tough week.
"We have to keep working hard and hope get some of our injured players back in.
"There is no magic formula but I have a brilliant group of players here. We will be ready and firing after the international break."
