Liverpool goalkeeper Adam Bogdan has held his hands up and admitted blame for his clanger that led to Watford's opening goal in their 3-0 victory over the Reds on Sunday.

Bogdan dropped the ball in his area when trying to complete what should have been a simple catch from a corner, allowing Nathan Ake to poke the ball home.

And although the Hungarian, who was standing in for regular No.1 Simon Mignolet, claims he was fouled by Ake as he went to grab the loose ball, he accepts that he should have never dropped it in the first place.

"I dropped the ball, of course," the 28-year-old told Liverpool's official website. "There's a mistake there.

"After that I felt my hand was on the ball and I was going to bring it out.

"Obviously he knocked it out of my hand -- but we are talking about split-seconds.

"Through the bodies of course it's hard (for the referee) to see. I'm not blaming anybody but myself to drop the first ball.

"Watford were really good but we -- and myself -- gave them a head start."

Odion Ighalo went on to score a brace as Liverpool lost for the third time under new German manager Jurgen Klopp, who actually has a worse Premier League record this season since taking over from the sacked Brendan Rogers than did his predecessor.

Rodgers mustered three wins, three draws and two defeats in league action, compared to the German's three wins, three draws and three defeats.

Klopp, who masterminded his side's impressive 4-1 win at Manchester City last month, said he was at a loss to explain Liverpool's inconsistency.

"If I could explain this do you think we would have done it?" said Klopp.

"But we'll work on it. And that's how the development sometimes works."
