According to Sky Sports reporter Keith Downie, Sunderland has quoted Bologna central defender Lukumi.

reporter Keith Downie said Sunderland has issued a offer to Bologna central defender Lukumi, who regards the 27-year-old Colombia international as the last piece of the team's defense.

Lukumi is eager to transfer to the Premier League, and his contract with Bologna has one year left, and the 24 million termination fee has expired recently, so Sunderland can negotiate. Sunderland has spent 135 million pounds this summer window.
