Adam Bogdan has accepted responsibility for his part in Watford's opening goal against Liverpool on Sunday, but has insisted he was fouled before Nathan Ake's strike.
Watford eased to a 3-0 win at Vicarage Road with stand-in goalkeeper Bogdan dropping an early corner which led to Ake poking home for the hosts after just three minutes.
However, the 28-year-old thinks the midfielder committed a foul in dislodging the ball from his hands - an assertion backed by Reds manager Jurgen Klopp - but still conceded he should have dealt with the danger.
"I dropped the ball, of course," Bogdan 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 to see. I'm not blaming anybody but myself [for dropping] the first ball.
"Watford were really good but we - and myself - gave them a head start."
Odion Ighalo's brace then consigned Liverpool to a fourth match without a win.
"It's not easy to recover after a goal like that in the first couple of minutes, it's never going to be easy," Bogdan added. "Of course it hit us and Watford managed to score another goal, which was another blow.
"We tried to come back into the game and I think we gave everything, although I don't think we played very well. But we tried."
Liverpool now have a worse Premier League record under new boss Klopp than predecessor Brendan Rodgers this season who mustered three wins, three draws and two defeats before he was sacked in October.
Klopp's league record now reads three wins, three draws and three defeats.
"If I could explain this do you think we would have done it?", said Klopp when asked to account for his side's inconsistency.
"But we'll work on it. And that's how the development sometimes works. There's no problem, you just have to react to the maximum and that's what we have to work on.
"The easy games everybody wins, the difficult games we have to win much more of than we have until now."
