Lille has undergone a significant tactical shift in their approach to defending, with the club switching to a new formation that aims to improve defensive stability and reduce the risk of conceding goals.

Previously, Lille had been known for its aggressive pressing style, which often resulted in high-risk attacks on opposing teams' defenses. However, with the team's defense struggling at times, manager Christophe Galtier decided to make a change in his tactics.

The new formation is designed to be more disciplined and structured, with a focus on solid defensive play. The team will have two central midfielders who will act as defensive linemen, while the back three will consist of four defenders, including a center-back and two wing-backs.

This new system is expected to give Lille more control over the ball, allowing them to maintain possession longer periods of time. Additionally, the midfielders will be able to provide support to the defense, helping to limit the amount of space available for opponents to attack.

One of the main advantages of this new formation is that it reduces the risk of conceding goals by minimizing the number of attacking players on the pitch. This means that the team can focus more on defending and less on creating chances for themselves.

Overall, Lille's switch to a new formation is a positive step forward for the team, and could potentially lead to improved defensive performances. With the right execution and discipline from the players, this new system has the potential to be a game-changer for the team in upcoming matches.
