Chelsea have reportedly added Napoli centre-back Kalidou Koulibaly to their ever-growing shortlist this summer, as they continue to chase down at least two new defenders.
The Blues boss Thomas Tuchel is keen to bring in reinforcements ahead of the new Premier League season with a huge shortlist of targets, especially in the defence with both Antonio Rudiger and Andreas Christensen departing the club.
The west London outfit are already targeting and in talks with a long-list of names, including Juventus star Matthijs de Ligt, Manchester City defender Nathan Ake, and Sevilla centre-back Jules Kounde in the defensive department.
