Chelsea made another bid of €50m (£45m) for Napoli defender Kalidou Koulibaly in the summer, according to the Gazzetta Dello Sport.
The Italian club’s president Aurelio De Laurentiis has confirmed previously that the Blues have offered close to €55m for the centre back, but it seems they made another attempt for the Senegalese international as they looked to strengthen their defence after the departure of club legend John Terry.
Antonio Conte opted to sign Antonio Rudiger from Roma for £29m in July, which likely ended their long term pursuit of Koulibaly. The Napoli defender has excelled under the guidance of manager Maurizio Sarri since joining from Racing Genk for £6.5m in 2014.
After struggling in his first season under the management of Rafa Benitez, he became an established starter under Sarri, helping the club to finish second and third over the past two years.
So far this season he has played 11 matches, helping the club to a 100% start in the league as they sit top of Serie A, with seven wins from seven games, with just five goals conceded.
