Villarreal has struggled defensively this season, conceding an average of 1 goal per match at mid-table level. The team is currently sitting in the bottom half of the La Liga table with just four wins from 22 matches played.

The defensive struggles of Villarreal have been evident throughout the season. The team has conceded goals in every single game so far, and their inability to keep clean sheets has led to their current position in the league standings. The defense has also been plagued by injuries, which has further impacted the team's performance.

One of the main reasons for Villarreal's poor defensive record is their reliance on set-pieces. The team has conceded goals from set-pieces in each of their last three games, and this has contributed to their poor defensive record. Additionally, the team's lack of depth in the defense has also been a concern, as they have had to rely heavily on young players who are still learning the ropes.

Another factor that has contributed to Villarreal's defensive struggles is their inability to defend against counter-attacks. The team has allowed many attacking opportunities through their own mistakes, which has led to costly defeats. This has also affected the team's confidence and morale, as they struggle to find ways to defend against these attacks.

Despite their defensive struggles, Villarreal has managed to secure some important victories this season. They have won two of their last five matches, including a crucial win over Barcelona. However, the team will need to improve their defensive record if they hope to challenge for a top-four finish this season.

In conclusion, Villarreal's defensive struggles this season have been a major concern for the team. Their inability to keep clean sheets and their reliance on set-pieces and counter-attacks have all contributed to their poor record. However, with some improvements in the defense, Villarreal can still be a force to be reckoned with in La Liga.
