“I know what people say about me and losing finals, that’s absolutely right,” said Klopp, who guided the five-time European champions to last season’s final, which they lost to Real Madrid. “But it’s the fourth final in that time as well we are in, that’s pretty special already.
“Last year we really felt we have to go back – we cannot let it stand like this, that’s not possible. Now we get another chance and we will go for that, of course.
“I’m not sure if it will happen again because it’s so special. When I saw the boys after the game and saw the tears in their eyes, that’s football. This club touches you like crazy, it’s like you feel much more than others in these moments.”
Wijnaldum said his team had shown “everything is possible in football”.
The midfielder replaced the injured Andy Robertson at half-time and scored twice, with Origi getting the winner.
“After the game in Spain we were confident we could score four and win 4-0,” he said.
“People outside doubted us. They thought we couldn’t do it. But once again we showed everything is possible in football.
“I was really angry that the manager put me on the bench. I just tried to help my team, I’m happy I could do that with two goals.”
The final is in Madrid on 1 June and will be the first since 2013 without a Spanish side involved – that after a run of seven finalists from that country in the past five seasons.
“Who’s going to the final? We are,” said Liverpool left-back Robertson, when asked about a running battle he had with former Reds striker Luis Suarez, whose kick injured the Scot and led to his half-time substitution. “That’s all that matters. Gini went on [for me] and scored two. I don’t care right now.”
Robertson also said this unlikely victory can help his side as they attempt to win the Premier League title on Sunday. They need to beat Wolves and hope leaders Manchester City drop points at Brighton to win their first league title since 1990.
“Fingers crossed,” he said. “We go to Sunday full of energy. It’s out of our hands but we’ve seen stranger things happen. Especially tonight.”
