Liverpool manager Rafael Benitez admitted he was stunned to see his side throw away a one-goal lead to lose 2-1 at Tottenham Hotspur.
The Reds lost for the first time this season to a last-minute Roman Pavlyuchenko strike on Saturday despite taking an early lead through Dirk Kuyt.
The defeat allowed Chelsea to pull level on points with the Anfield club at the top of the table and afterwards Benitez blamed his side's inability to convert their chances.
He said: "I can't believe we lost that game, it's as simple as that.
"We hit the crossbar and had a lot of opportunities. It's always important to create chances but it's more important to score.
"We're really disappointed, it was really bad luck. Conceding those two goals is difficult to explain.
"We were controlling everything so I was pleased. We knew we'd have to score the second goal. If we'd scored that they were beaten.
"We had four clear chances in the second half but you have to take your chances.
"We could easily have been 4-0 up after 60 minutes."
