The French striker's return to Arsenal is one of the most significant signings in recent years, and it has had a major impact on the team's tactics.

In the past, the Gunners relied heavily on their attacking trio of Pierre-Emerick Aubameyang and Alexandre Lacazette, but both players have been struggling with injuries this season. Jean-Louis Lelouc, the club's manager, decided to make a big change by bringing in the former Lyon forward.

Lelouc made some tactical adjustments after the player returned from injury, which allowed him to play more centrally and create space for his teammates. He also gave him more freedom to run behind the defense, allowing him to exploit the weaknesses of opponents' defenses.

As a result, the team's offensive play has improved significantly. The likes of Gabriel Martinelli and Nicolas Pepe have benefited from the changes, as they have been given more opportunities to shine. This has led to a more balanced attack, with the team scoring more goals than ever before.

However, the success of Lelouc's tactics has not come without its challenges. There have been instances where he has been criticized for being too aggressive or pushing the team too far out of their comfort zone. But overall, the results speak for themselves, and Lelouc's decision to make these changes was definitely worth it.

Overall, the signing of Jean-Louis Lelouc has been a game-changer for Arsenal, and it will be interesting to see how the team continues to develop under his leadership. With the likes of Aubameyang and Lacazette back in form, there is no doubt that the team will continue to perform at a high level, and Lelouc's contributions cannot be overstated.
