In a bid to improve its tactical approach and stability, Lille has shifted from a 5-4-1 defence system to a 6-2-1 formation. The change comes as the French side seeks to maintain their position in Europe's top flight while also preparing for potential changes in the league.

The 6-2-1 formation is one of the most advanced defensive formations in the world, featuring a combination of two defensive lines and two attacking lines. This system allows players to play with both feet, which helps to reduce the risk of injury and provides more opportunities for movement on the field.

Under this new formation, Lille will be able to deploy their defenders in different positions to match the opposition's strengths and weaknesses. For example, they may use their centre-backs in the backline to pressure the opponent's midfield, while their wing-backs can provide cover behind them.

However, there is still some uncertainty about how effective the new formation will be against opponents who have adapted to the 6-2-1 system. Despite the shift, Lille remains confident that they can adapt to any changes in the league and continue to stay competitive.

Overall, the move towards the 6-2-1 formation represents a significant step forward for Lille and could help them to compete at the highest level. As the season progresses, it will be interesting to see how well the team performs under this new system and whether they can maintain their lead in the Premier League.
