Jurgen Klopp was disappointed after watching his young Liverpool squad lost 3-1 to Swansea City on Sunday at Liberty Stadium.
Jack Cork and Adre Dede Ayew’s brace sailed victory for the Swans as Christian Benteke pulled one for the Reds.
Liverpool went a man down after Brad Smith was shown a red card and the Reds performance was below average as expected of them against Swansea City who are desperate in need of a win to maintain top flight campaign.
And Klopp was displeased to watch his side underperformed.
“We deserved the defeat and they deserved the win but I think a big part of this result was our performance so we have to accept this, recover and prepare again and play much better.
“Our performance was not as good as possible. With this line up, we tried to bring fresh legs and fresh minds.
“I’m only frustrated and disappointed because I know we could have played better.
“It’s not important now but if we could have played a little bit better, closer to our 100 per cent then it would have been a completely different game.”
Winning Europa League will guarantee automatic qualification to the Champions League and Liverpool made eight changes from the side that lost 1-0 in first leg of Europa game against Villareal last Thursday.
The Reds will play the return leg at Anfield this Thursday and Klopp debunked claims that he prioritise European competition than the Premier League.
“It’s the Europa League, then next Sunday, it’s the Premier League. Do you really think we say ‘let’s put everything in this game and ignore the rest of these games’ that’s not how we can work.
“We played really well in the last few games with different line-ups and today we didn’t and that’s less surprising than the good games we played with ten changes and things like this.
“After Bournemouth, after Stoke, after all of these games, everyone says ‘how good are these young players?’ and they are good, but that’s how it is.
“Life as a professional footballer player is not always a honeymoon, so you have to prove yourself and deliver.
“Today, it didn’t work too well but that’s not a problem for the future, it’s only problem for today… It’s not about the squad or something, it’s only about today.”
