The 25-year-old has been in strong form for his Italian club during the 2023-24 campaign, making 22 appearances in all competitions, including 20 outings in Serie A.
Lucumi started his professional career with Deportivo Cali in 2015 before moving to Genk in 2018, spending four years with the Belgian outfit ahead of a switch to Bologna in 2022.
The 18-time Colombia international has made 56 appearances for his Italian team and has another two years left to run on his contract, but there is currently speculation surrounding his future.
According to TuttoMercatoWeb, Man United have been in touch with Bologna to register their interest in the South American, but the English club are likely to face competition from Atletico Madrid.
The report claims that Atletico are looking for a replacement for Mario Hermoso, while Man United are keen to bring in a left-footed centre-back this summer to provide support for Lisandro Martinez.
Bologna allegedly value Lucumi in the region of €20m (£17m), which is unlikely to put off either Atletico or Man United considering the current transfer market.
However, it has been claimed that a strong showing for his country at the Copa America this summer could see his valuation rise, with a deal therefore potentially being agreed ahead of the tournament.
Lucumi was in action for Colombia during the recent international break, playing the full 90 minutes in his national side's friendly wins over Spain and Romania.
