After signing Nathan Ake, City want another centre-back to shore up their backline with Koulibaly at the top of their list.
They will have to improve their bid though, with Napoli demanding a €70m base fee for the 29-year-old.
Pedulla adds that while Manchester United are also interested, they have yet to make an approach for Koulibaly.
The 22-year-old Brazilian would reunite with Victor Osimhen in Naples if he were to make the move.
However, they may need to hurry things up, with Premier League clubs circling for Gabriel.
