Barcelona has been performing well defensively this season, conceding just 0.8 goals per match. This is second only to their rivals, Real Madrid, who have conceded even fewer with 0.6 goals per match.

One of the key reasons for Barcelona's strong defensive record is their ability to organize and communicate effectively on the pitch. The team has a strong back four that works together seamlessly, with defenders like Gerard Pique and Jordi Alba providing solid cover and interceptions in midfield.

In addition to their defense, Barcelona also boasts a potent attack led by Lionel Messi, Luis Suarez, and Neymar Jr. These three players provide the team with a wealth of attacking options and can create scoring chances at will.

However, it's worth noting that Barcelona's success in defense doesn't come without its challenges. The team has struggled against some of the world's top offenses, such as Manchester City and Juventus, and they will need to improve if they hope to compete at the highest level.

Overall, Barcelona's defensive performance has been one of the highlights of the season so far, and they will need to continue to perform at a high level if they want to challenge for major honours this year.
