Chelsea midfielder Jorginho admits he was anxious about seeing Kalidou Koulibaly complete his move from Napoli.
Jorginho played with Koulibaly at Napoli before his own departure for London.
He told Sky Sports: "We hope to play together another four seasons (laughs).
"I think it was a very positive signing for the club, because he is not only a strong player who will help us a lot on the pitch, but I believe that he will help a lot in the locker room, considering the person he is.
"He is an exceptional guy. During the negotiations for his move I called him urging him to come. And I am very happy that it happened."
