The player has joined Slavisa Jokanovic’s side on a three-year deal with the option for a further 12 months.
In an interview with the club’s official website Djalo said “for me it is a proud moment. It’s a big club, an emblem of the city, and for me it’s a proud moment. Quite simply, I want to be here, I want to work here, I want to grow as a person and a footballer at this great club.”
As a youngster, Djalo also spent time on the books of Italian giants Juventus, though he never made a first team appearance.
