Liverpool manager Jurgen Klopp says Champions League semi-final opponent Villarreal fully deserves its place in the last four and its coach Unai Emery is the "King of the Cups".
Liverpool drew 3-3 with Benfica in its quarterfinal second leg on Wednesday to go through to the semis with a 6-4 aggregate scoreline.
The win sets up a meeting with Villarreal which pulled off a shock victory over Bayern Munich in the last eight.
"I saw the results, the game was very impressive. I only picked up pieces but to beat Juventus and Bayern Munich they deserve to be in the Champions League semi-finals," said Klopp.
"Unai Emery is the king of the cups, it is unbelievable what he is doing. But give me a bit of time to prepare it properly," he added with a grin.
Emery won the Europa League three times with Sevilla and triumphed in the same competition with Villarreal last season and he won four domestic cups with Paris St Germain.
While the Spaniard's time in charge at Arsenal was a disappointment, he still managed to take the London club to the Europa League final in 2019.
Klopp was in a forgiving mood about his team's leaky performance against Benfica at Anfield where as well as conceding three goals it also saw two efforts from the visitor ruled out for offside.
"The day we qualify for the Champions League semi-final and I'm not happy please come and knock me out," he said.
"We made seven changes. The situation was the last line had never played together and it was about details, staying 100% concentrated.
"It was not exactly what we wanted but it is absolutely not important because if we played the best game of the season tonight it wouldn't have made it more likely to get to the final. We are through and that's all that matters and I'm really happy," he said.
Liverpool's defence, featuring Ibrahima Konate and Joel Matip in the middle and Joe Gomez and Kostas Tsimikas at fullback, was opened up with some ease by the Portuguese side but Klopp said that was understandable.
"The one thing we knew is it will be hard as the last line never played together. You lose the boys like Virgil (van Dijk) and these things are normal. This is not a problem. Benfica kept believing and kept going that's all. It was important we could make changes and still be successful. That's fine."
