Jurgen Klopp admitted he was unhappy with Liverpool's performance after they fell to a 2-0 defeat away to Premier League leaders Leicester City.
After a lively but goalless opening period at the King Power Stadium the visitors succumbed to two Jamie Vardy goals in 11 minutes. The striker broke the deadlock after 60 minutes with a stunning 25-yard volley before taking his season's league tally to 18, reacting fastest after Shinji Okazaki had a shot saved by Simon Mignolet.
Klopp acknowledged the quality of Vardy's opener but the manager felt his team had been below-par on the night as they dropped to eighth in the table while the Foxes remained three points clear of Manchester City at the summit.
"It's rare a journalist says something more positive than the manager," Klopp told the BBC's Match of the Day.
"I'm not too fine with our game today. We could have played much better. We had a few shots where we could pass and a few passes where we could shoot. We created half-chances but not real chances."
He said of Vardy's long-range effort: "It was a world-class goal from Jamie Vardy. Today would have been a good day to show we are ready for this. I need a few more seconds to calm down. I have to watch it again."
Liverpool rarely threatened and Christian Benteke had another anonymous outing from the bench to further cast doubt over his suitability in Klopp's team.
The German felt his players could have taken something from the game but ultimately their decision making cost them.
"We had opportunities in the box but we didn't find the right decision often enough," he told a news conference. "The longer the game was we didn't get cooler, the decisions didn't get better. We had the ball in their box and didn't shoot.
"One second later Vardy shoots from 35 yards and the ball was in. This says most about the game. I don't feel too good."
