Defender Kalidou Koulibaly says he finally made his Premier League move to join Chelsea because they were "the only club that really wanted me".
Koulibaly, 31, revealed former Chelsea boss Antonio Conte first made contact with him in 2016, but said: "I'm not a player who wants to go fighting with the club to leave."
He spent eight years at Napoli.
Senegal captain Koulibaly said he had been encouraged to join Chelsea after a chat with Blues legend Gianfranco Zola.
He added "friendly pressure" had come too from current Chelsea players, his former Napoli team-mate Jorginho and Senegal goalkeeper Edouard Mendy, and looked forward to competing against the Premier League's best forwards.
