Pep Guardiola has identified the Italy international midfielder as a top target for the summer window, with Goal having revealed back in April that a big-money approach was being readied.
A €50m (£44m/$59m) offer has since been tabled, but that was swiftly knocked back by Napoli president Aurelio De Laurentiis.
He is refusing to relax his stance when it comes to the possible sale of a prized asset, with it now unclear whether the 26-year-old will get a dream move or if City will shift their focus elsewhere.
Jorginho’s representative, Joao Santos, told CalcioNapoli24 on a frustrating saga: “Jorginho is a Napoli player. Napoli and Manchester City have not yet reached an agreement, as there is around €10m distance between the demand and the offer.
“Now City are working on Plan B. The player is waiting for Napoli’s decision. He has another two years on his contract and we will not renew it.
“Jorginho’s contract is owned by De Laurentiis and, as of today, he remains a Napoli player. We won’t be hypocrites here, any player would love to go and play under Pep Guardiola.
“I don’t have to say anything to the president, as if he is convinced that it’s a good deal to sell, then he will. If he feels Jorge can continue to do a good job with Napoli, then he’ll aim to keep him.
“Jorginho is a professional, but this is the opportunity of a lifetime for him and his family. If he doesn’t go to Manchester City, he won’t be very happy.”
Jorginho has been with Napoli since 2014, taking in 160 appearances for the club and scoring six goals.
He is considered to be the ideal addition to a midfield department at the Etihad Stadium which already includes proven performers such as David Silva, Fernandinho and Kevin De Bruyne.
