Sunderland have made a bold move in the transfer market, submitting an official bid for Bologna’s Colombian centre-back Jhon Lucumí as they look to reinforce their backline ahead of the new Premier League campaign.

The 25-year-old defender is reportedly enthusiastic about the prospect of joining the Black Cats, viewing it as an opportunity to embrace a fresh challenge in England’s top flight. Sunderland’s sporting project has been key in convincing Lucumí, who has attracted attention for his consistent performances in Serie A.

Bologna, however, remain reluctant to sanction a sale. The Italian club are eager to keep hold of their defensive mainstay, especially after his release clause expired earlier this summer, giving them firmer control of his future. Their stance signals a potential tug-of-war in the weeks ahead.

With Sunderland pushing to bolster their squad for a competitive Premier League return, Lucumí has emerged as a priority target — but prising him away from Bologna will require significant negotiation.
