Sevilla won their third consecutive Europa League in Basel, securing a 3-1 win after an excellent second half showing.
The La Liga side were comprehensively outplayed by Liverpool in the opening 45 minutes, but a strike 17 seconds into the second period from Kevin Gameiro pulled the tie level after Daniel Sturridge’s excellent opener.
Coke netted twice to secure the victory, and the trophy, as the Reds looked lacklustre and abject in the second half, and Klopp has admitted he was frustrated by the showing.
The German boss believes his team were nervous, but he wants them to learn from the experience of playing in a final and become ‘stronger’ in the coming years.
He told BT Sport: “We started off really well, we scored a wonderful goal, had our chances, had a disallowed goal.
“The second half is not about the first goal it’s about not concentrating enough for the second goal.
“We did not defend well and were nervous and that shows our development is not as good as we hoped but we will use this experience to be stronger and I am sure we will be stronger if we use it in the right way, but for tonight it is disappointment and frustration.
“Tonight we couldn’t reach the level and it is my job to help the boys use these opportunities. I am responsible for this performance too, so no criticism for my players tonight.”
James Milner, who captained the Merseyside club in Jordan Henderson’s absence, shares the same view as Klopp concerning the second half performance.
The England international said: “I am devastated at losing the game but I think the most disappointing thing is in the second half we didn’t show what we are about, we played nowhere near our abilities, that’s the biggest thing for me.
“We were ready, we made sure we wanted to do the right things, everyone was switched on, we just didn’t show it. We have come out and given a sloppy goal away in the first few seconds of the second half and never really got back in the game after that.”
