Kalulu continued to perform well for Milan last season, earning himself a place in the starting lineup once again. Despite facing competition from other centre-backs like Suso and Alessio Romagnoli, Kalulu proved himself to be a valuable asset for the team, helping them to finish second in the Serie A table and reach the semi-finals of the Europa League.
