Klopp, who has made his displeasure about early kick-offs known regularly during his reign at Anfield, watched Fernando Llorente fire the Swans into a 2-0 lead early in the second half on Saturday.
Though Roberto Firmino scored twice to pull the Reds level, Gylfi Sigurdsson popped up to send all three points back to South Wales, leaving Klopp immensely frustrated.
And the Liverpool boss admitted his frustration at the relative lack of intensity among the home fans for the 12.30pm start, saying:
‘It was very, very quiet today.
‘There is a lot of frustration and disappointment. You could hear in the stadium it wasn’t the most entertaining in the first half.
‘Maybe other games we deserved more to lose. This was a big opportunity for us – (we) gave them the opportunity to win. It’s frustrating.’
With Chelsea playing Hull at Stamford Bridge on Sunday, Klopp is likely to watch his side lose further ground on the leaders this weekend.
But he is determined not to allow his squad to wallow in self-pity.
‘It’s damaging if this defeat influences us,’ he said. ‘We have lost, but it has to feel really bad. And it does. We have to use it and react.
‘I don’t look for luck but it’s obvious we didn’t have a lot today. We showed when we are really on track, we are a strong side.’
