Villarreal surprised everyone by knocking Bayern Munich in the Champions League.
The Spanish side drew 1-1 in the return leg at Munich yesterday which helped them cement a place in the semi-finals.
The Yellow Submarine won 2-1 on aggregate after their last week’s victory over Bayern at El Madrigal.
Last season they won the Europa League by beating Manchester United in the final to secure the last spot in this year’s edition of the Champions League.
Emery said: “To achieve something, you have to do important things and beat the favourites. That [round of 16] game against Juventus gave us a lot of confidence. In the semi-finals, we will try to create circumstances so that we have our chances. Liverpool are a great team and Benfica, too. It will be a great semi-final to enjoy.
“The feeling is unbeatable. We are achieving important things. It was a huge game but the first leg already said a lot about how we were going to respond today. We were perfect in defence.
“When we scored the goal, it came at a very critical moment – because when Bayern score a goal, they have shown in other games that they can then score two or three.”
