Manchester City have been left furious by Jorginho's controversial move to Chelsea , with club sources citing "an unprecedented lack of professionalism" on the part of Napoli chairman Aurelio De Laurentiis, goal.com reports.

The story quoted is sounds like a detective: "City say Jorginho was given an ultimatum by De Laurentiis that amounts to the midfielder effectively being "bullied" into signing for Chelsea. The Premier League champions had reached an agreement with Napoli more than a fortnight ago , and had ironed out personal terms with the 26-year-old midfielder long before the end of last season.

Jorginho and his agent had made it clear to City officials that he was determined to play for the club and work with Pep Guardiola. However, City believe he was left with no choice but to sign for Chelsea.

For the past several weeks the Londoners had been trying to negotiate a compensation package with Napoli for coach Maurizio Sarri, who had been relieved of his duties by De Laurentiis and was lined up to replace Antonio Conte.

Talks had reached an impasse, however, and it soon became clear to De Laurentiis that he would only receive the desired €8 million pay-off for Sarri from Chelsea if it also included in a deal for Jorginho, whom Sarri wanted to bring to Stamford Bridge.

At this point, City sources claim, De Laurentiis reneged on the deal he had personally signed off, as the Chelsea package was the only way to receive the money for Sarri".

Football world is usually full of rumours, but this is something I can believe. De Laurentiis is quite a clever politician who is really influential. And not everyone can say 'no' to him. Probably this can be the case. I can imagine how thankful the player is to De Laurentiis and Jorginho could easily do what he was told to do.
