MILAN -- Inter's recent Champions League performance raises serious concerns as they struggle to compete on the European stage. The Nerazzurri have lost seven of their last eight matches in the tournament, with crushing defeats against both Real Madrid and Club Brugge in the current league phase.

On Tuesday, Inter suffered a 4-3 defeat at San Siro, showcasing alarming defensive weaknesses. While they dominate domestically, their European form tells a different story. Here are the three biggest concerns following the match:

1. Defensive Issues
   Inter's defense has become a significant liability, conceding a total of 14 goals in just eight matches across competitions. With Manuel Akanji leading the backline after the departures of Stefan de Vrij and Francesco Acerbi, his inconsistent performances raise questions. The latest goals conceded against Club Brugge highlighted the team's lack of physical readiness and defensive cohesion.

2. Woeful Goalkeeping
   For the second consecutive Champions League match, an Inter goalkeeper made a critical error, allowing Club Brugge to score a pivotal goal. While Josep Martinez made several saves, the mistakes have prompted speculation about Ivan Provedel potentially stepping in as the starting goalkeeper in the coming weeks.

3. Lautaro's Missed Opportunity
   Captain Lautaro Martinez had a crucial chance to alter the game's outcome but failed to score against his former teammate, Yann Sommer. Despite netting two goals, he couldn’t match the performance of Nicolò Tresoldi, who shone as the MVP for Club Brugge.

As Inter prepares for their remaining six matches in the group phase, significant adjustments are necessary to reclaim their status as serious contenders.
