Barcelona's defensive woes have been well-documented this season, with the club conceding three goals in just two matches. The Catalan giants' struggles at the back have been a cause for concern, and there is a need for a significant defensive overhaul.

The first issue that needs to be addressed is the lack of consistency from Barcelona's defense. In their opening match against Real Madrid, they conceded a late equalizer, while in their second match against Sevilla, they were beaten by a brace from the visitors. These results highlight the fact that Barcelona's defense has not been as solid as it was last season.

Another problem is the reliance on Lionel Messi and Luis Suarez to score goals. While both players have had impressive seasons, they cannot single-handedly carry the team. Barcelona will need to find ways to balance their attack and defense if they want to compete for major titles this season.

The third issue is the lack of depth in the squad. Barcelona has struggled to keep up with the pace of La Liga this season, which has taken a toll on their defense. If the team wants to improve, they will need to bring in new signings or reinforcements to strengthen their defense.

In conclusion, Barcelona's defensive woes are a serious concern for the team. They need to address these issues before they can hope to compete for major trophies this season. With some strategic changes and additions to their squad, Barcelona can turn their defense around and become a force to be reckoned with once again.
