AS reports that Barcelona are monitoring Lucumí.
The Spanish giants are in the market for a new centre-back and the 26-year-old could be an option.
After Bologna sold Riccardo Calafiori to Arsenal, Lucumí has taken on more responsibility in Bologna's defense and impressed greatly in the opening season.
Barcelona's search is linked to Denmark international Andreas Christensen, 28, set to move in 2025.
