Manneh joined Mjallby from Gambia's Wallidan FC after a successful trial in January 2024. During his time with Mjallby, he scored two goals and provided one assist in 21 Allsvenskan matches last year, starting eight of those matches.

This season, Manneh has started strongly, just like his team. He has scored five goals and two assists in seven Allsvenskan matches, all of which he started.

Mjallby's sports director, Hasse Larsson, has confirmed that there is interest in Manneh, who has a contract until 2027.

Several teams, including Wolves, Brighton, Olympiakos, and FC Cincinnati, are keeping a close eye on Manneh's performance, with their scouts regularly attending Mjallby's games.
