William Saliba has had a significant impact on Marseille's attack and its aftermath. As the manager of the club since 2018, he has been instrumental in transforming Marseille into one of France's most successful teams.

Saliba's first season at the helm saw Marseille finish second in Ligue 1, their best league position in years. He then guided them to a Champions League semi-final appearance in his second campaign, where they were eliminated by Barcelona in the quarter-finals.

During this time, Saliba implemented a tactical approach that prioritized possession and attacking play. This strategy was particularly effective against weaker opponents, allowing Marseille to secure multiple wins and draw during the season.

The success of this tactical approach was evident in Marseille's performances throughout the year. They won six matches out of seven in Ligue 1, with only two draws and one defeat. Their impressive defensive record also stood out, with just three goals conceded across all competitions.

However, despite these achievements, Marseille did not win any major titles during Saliba's tenure. The team struggled to compete with top-tier clubs like Paris Saint-Germain, Olympique de Marseille, and Lyon, who dominated the league and cup competitions respectively.

One area where Saliba made notable improvements was in the transfer market. Under his leadership, Marseille strengthened their squad with several key signings, including defender Alphonso Davies and midfielder Adama Traore.

Despite these positive developments, Marseille's performance dipped slightly towards the end of the season. In the final match of the season, Marseille lost 2-0 to Monaco, ending the campaign with a 5th-place finish in Ligue 1.

In conclusion, while William Saliba has played a crucial role in Marseille's recent success, there is still room for improvement. With strong performances in various competitions and a solid foundation built over his tenure, it appears that Marseille will continue to challenge for titles in the coming seasons under Saliba's guidance.
