Marseille, the French football club, has been one of the most talked about teams this summer transfer window. One player that has caught the attention of fans and experts alike is Corentin Tolisso, who was signed from Bayern Munich for a reported fee of £25 million.

Tolisso, who is known for his defensive skills and ability to read the game, is expected to add much-needed depth to Marseille's squad. However, the signing of Tolisso comes at a time when Marseille is also facing some internal issues within their squad.

The team's core signing, however, is not just Tolisso but also the return of former captain Florian Gueydan. Gueydan, who has been out of contract with the club since last season, will be back on loan until the end of the season, bringing experience and leadership to the team.

Despite these signings, Marseille still faces challenges ahead of them. The club's financial situation remains a concern, and they need to find ways to balance their budget while retaining key players like Nabil Fekir and Dimitri Payet.

Furthermore, the club's manager, Lucien Favre, will have to work hard to integrate new players into the team, as well as keep the existing players motivated and focused. With so many factors to consider, it seems that the summer transfer window may not be over yet for Marseille, and we can expect to see more exciting developments in the coming weeks.
