In the 2018 Copa Libertadores tournament, São Paulo emerged as one of the biggest surprises on the global football stage. The Brazilian club secured their spot in the final after defeating Atlético Nacional in the quarterfinals and then defeated Flamengo in the semifinals.

But what set São Paulo apart from their competitors was not just their individual players or tactical formations but their wing defense system. This system has been instrumental in the team's success and is credited with helping them dominate matches and score crucial goals.

The wing defense system at São Paulo is characterized by two defensive lines that extend beyond the wings of the team. These lines are positioned deep in the opponent's half, often overlapping each other, creating a wall of pressure that makes it difficult for opponents to break through.

One key player who has played a pivotal role in this defense system is Jonathan Calleri. The Argentine midfielder is known for his physicality, agility, and ability to play both inside and outside the box. He is also known for his leadership qualities and his ability to inspire his teammates.

Calleri's presence on the pitch is crucial because he can play both as a defender and a forward. When he plays as a defender, he is able to provide cover for his teammates and help prevent对手 from scoring. When he plays as a forward, he can create chances for his teammates and put pressure on the goalkeeper.

Another important aspect of the wing defense system is its flexibility. The system can be adjusted depending on the opposition's strengths and weaknesses. For example, if the opposition has a strong winger, Calleri can shift deeper into midfield to protect his defenders. If the opposition has a strong striker, Calleri can move forward to create space for his teammates.

Overall, Jonathan Calleri's wing defense system has been a key factor in São Paulo's success in the Copa Libertadores tournament. His physicality, leadership, and adaptability have made him an essential part of the team's defense, and his contributions have helped them dominate matches and secure their spot in the final.
