Manzambi had a promising season with Freiburg, scoring two goals and providing two assists in 11 Bundesliga matches. He has also scored one goal in four international matches for Switzerland.
It appears that Freiburg may lose Manzambi, as he could be transferred to one of these top clubs. Chelsea's interest in Manzambi is being explored through a partnership with their sister club, Strasbourg. This would allow Manzambi to gain experience playing in the French league, Ligue 1, and potentially lead to a transfer to Chelsea in the future.
Borussia Dortmund had already considered signing Manzambi last summer, and it seems they are still interested in bringing him to the team.
It's worth noting that no official announcements have been made about Manzambi's future, and the situation is still being discussed.
