Benfica really surprised with their brazenness away against Liverpool! Probably no one has played Liverpool like that before this season. Only Milan managed to score 2 goals against Liverpool, so we could say that Benfica set a record by scoring three goals. It will be interesting to see how Liverpool play Villarreal.
I was surprise with Benfica can scoring 3 goal on Anfield Stadium and they have more motivation although have loss first 3-1 before make draw become 3-3, maybe if have draw or loss under 1 goal on first leg will make between Liverpool vs Benfica most interested like Real Madrid vs Chelsea match. I think can't make easy predicting on semifinal between Liverpool vs Villareal because Bayern Munich and Juventus as top team eliminating by Villareal and looks careful for Liverpool.
Although Liverpool did not play all of their main players in the second leg match, the quality of the players Liverpool still quite good. So the fighting
spirit of the Benfica players was extraordinary in the second leg match, they can score 3 goals against Liverpool which is a good achievement.
Because not many teams can score many goals against Liverpool, because Liverpool are famous for their solid defense. Benfica's appearance was
very different when they played in the first leg, this second leg's appearance was Benfica's attack was much more effective. Even though Benfica
only had 33% possession of the ball and took only 6 shots, but they were able to score 3 goals which was extraordinary. Therefore, Benfica's exit
from the Champions League was quite honorable, because they were able to put up a fight even though they lost in quality to Liverpool.
Regarding Villarreal who will be Liverpool's next opponent, as you said, Liverpool have to be careful. Because Villarreal was able to get rid of
Juventus and Bayern, it was an admirable achievement, Liverpool could not underestimate Villarreal. Although Villarreal's performance was not
so good in La Liga, but Villarreal's appearance in the Champions League was very different, they turned into a strong team. Liverpool must find
a way to break through Villarreal's solid defense, but with the quality of the forwards that Liverpool have, and also with Klopp's well-known
strategy, Liverpool should be able to penetrate the Villarreal defense and be able to beat Villarreal.
