The Holland international’s future at the Etihad Stadium has been the subject of speculation for much of the summer after he failed to agree terms over a new deal.
De Jong was signed from Hamburg in January 2009 for £18million by former boss Mark Hughes and has been a regular name in the starting lineup under Roberto Martinez during his two-and-a-half year reign.
Rumours of a move to Chelsea and Arsenal have surfaced during the past few months but the 27-year-old has stated his desire to remain with City despite starting just 11 league games last season.
“My contract runs for another year, so I’m in a pretty good position,” he said.
“I would like to stay. I’ve been at the club for more than three years and I’m enjoying myself.
“I have won the two biggest trophies in England – the FA Cup and the league title.
“I’ve seen the club develop from total chaos with the training facilities into a top club, and that’s very satisfying to see.”
Meanwhile Mancini has been dealt a blow in his pursuit of Fernando Llorente after Athletic Bilbao revealed City must match the £30 million release clause in his contract if they are to bring the striker to England.
The Italian is desperate to bolster his frontline with Edin Dzeko set to depart and has his eyes set on 27-year-old Llorente who struck 24 league goals for the La Liga side last season.
But Bilboa president Josu Urrutia revealed they won’t accept a penny under his valuation from the Premier League champions saying:“He is a key player and we would not accept less.
“The supporters would not accept this.”
