The Lyon team has made some significant changes in their tactics to 4-4-2 after the return of Lavezé for his forward boost. The move is aimed at improving the team's defensive stability and reducing the risk of injuries.

In the previous game, the Lyon midfield struggled to contain the attacking play of Marseille. This was due to the lack of creativity on the part of the team, as they were unable to find the back of the net against the opposition. To address this issue, the team decided to make a few changes in their tactical approach.

One of the key changes that have been made is the switch to a more traditional 4-4-2 formation. In this system, the four central defenders will be responsible for defending the center of the pitch while the two wings will defend the left and right sides respectively. This change is designed to provide better coverage and prevent opponents from finding easy goals.

Another key aspect of the new tactical approach is the introduction of a higher number of attackers. With Lavezé returning to the team, the team believes that it can now create more opportunities for scoring. Therefore, they have added more players into the squad who can contribute to the attack.

Overall, the decision to adopt a 4-4-2 system has been well-received by the Lyon team. The move has improved the team's defensive stability and reduced the risk of injuries. However, there is still room for improvement, especially in terms of creativity and counter-attacking strategies. As such, the team will continue to monitor the results of the new system closely to see how effective it is in achieving its goals.
