Rafael Benitez admitted Liverpool had missed a golden opportunity to land a significant blow in the title race after being held to a goalless home draw by Fulham.
The Reds dominated possession at Anfield, but were unable to find a breakthrough on a day when none of the other members of the Premier League's top four managed to record a victory.
Benitez's men couldn't find the finishing touch in a game that could have taken them two points clear at the top of the table.
"It was a bad day. We weren't playing well, we didn't have enough energy and we did not pass well," bemoaned Benitez.
"But we had three good opportunities even though we played badly.
"We started the second half really well. We had more intensity and more determination.
"There is a bit of frustration. We are disappointed because when we got to the dressing room we were told that Chelsea drew and Arsenal lost.
"Clearly it is an opportunity lost, but it's also an opportunity lost for Chelsea."
