Sunderland has made an official offer to the Italian club Bologna to sign Colombian defender John Lucumi, according to reliable journalist Fabrizio Romano via his official account on the platform 'X'.

This move comes as part of Sunderland's desire to strengthen its defensive line in preparation for competition in the Premier League.

The source revealed that Lucumi is eager to join Sunderland's project, as the player aims to start a new phase in his professional career by experiencing the English league, one of the most prominent competitions in the world.

On the other hand, Bologna shows a strong desire to retain Lucumi's services, especially after the expiration of the release clause in his contract, which gives the Italian team full control over the player's future.

It seems that Bologna will not easily part with Lucumi, making Sunderland's task of signing him difficult given the Italian club's insistence on keeping him, despite the official offer made.
