The summer transfer window is one of the most important events in football, as it allows clubs to sign key players and strengthen their squads for the upcoming season. However, this process can also be very difficult, especially when there are no clear signs or indications from the clubs themselves.

In Marseille, where the core signings have been made, they have proven to be successful. The club has signed several high-profile players who have brought new energy and depth to the squad. For example, Marseille have signed striker Yannick Vidal, defender Mathieu Flamini, midfielder Alphonse Areola, and winger Mathieu Valbuena.

However, despite these impressive signings, there is still room for improvement. Marseille have struggled to attract quality players in recent years, which has left them vulnerable to competition from other teams in the league. This lack of talent may be partly due to the club's limited budget and lack of resources.

To overcome this issue, Marseille will need to invest more heavily in the transfer market this summer. They will need to bring in more experienced players who can help them improve on their current form. Additionally, they will need to work closely with their scouts and medical staff to ensure that they make the right decisions about signing new players.

Overall, while the summer transfer window can be a difficult time for many clubs, Marseille's success story suggests that there is still hope for them to succeed this year. With a strong core of players and a talented coaching staff, Marseille could potentially become one of the top teams in Europe next season.
