The match you don't expect with an absolute favorite, Liverpool, and the surprising Spaniards of Villarreal led by European cup specialist Unai Emery.
Three years after the Champions League triumph against Tottenham, Jurgen Klopp's Reds are back in the semifinals: the current opponent is the yellow submarine, a real revelation of the tournament after having eliminated Juventus and Bayern Munich.
The first to admit that Villarreal is no longer a surprise but a reality of European football is Klopp who does not stop praising the work done by his colleague Emery.
"Tomorrow will be a very difficult match, the opposite would be abnormal.
It is impossible for a Champions League semi-final to be simple - said the German coach - I already had respect for Emery and his team, but after having carefully analyzed Villarreal, I said 'Wow!'.
He is a coach obsessed with details, his team is able to react to any kind of result, he has a plan whether he is ahead 1-0, or if he is behind.
He is a world-class coach, who does an incredible job. "A Villarreal perhaps underestimated by the other opponents:" It is possible that they have been underestimated by Juventus and Bayern Munich-adds Klopp-but that won't happen with us.
Of course they want to make it to the final, but it's the same for us too.
There will be times when we will suffer, I know.
We don't need to get nervous, but we know how to make them suffer.
A surprising Villarreal, but which, as indicated by his coach, did not win the Champions League semi-final by chance: "every team that is in the Champions League semi-final is there because it deserves to be there. Liverpool know that we have a great European presence, that we were able to eliminate two great teams. Now the surprise effect is gone, against Liverpool it will be even more difficult. The Reds - adds Emery - know it will not be easy to face us, they will obviously feel like favorites but they will have respect for us. This is the best Liverpool I've ever been in. I see it as an added motivation, trying to beat the best Liverpool ever.
It will take concentration on every aspect of the game.
We play against the favorites to win the competition, but - concludes the Villarreal coach - we want to be protagonists.
It will not be a foregone conclusion, our opponents may be superior to us, but we have our own recognizable game identity and our weapons to be able to compete.
I live this semifinal so naturally ".
