They knew they wouldn't be able to win by playing open so they kept defending and kept defending but it's quite effective now because I saw throughout this game Liverpool couldn't create any good chances until this minute
Villareal had a good defense, but they didn't attack as expected. It was so boring that I didn't think they deserved to be in the final. Take a look at their stats so far, you'll know what I mean. The first half is almost over, the score is still 0-0.
