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.
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.
