The Dutchman has impressed in the Premier League since joining Everton from Atletico Madrid last summer.
“I have heard the reports, but nothing is serious as yet,” Heitinga told De Telegraaf.
“City have ambitions and I am always looking to move to a bigger club.
“But I have a contract for four years, without any get-out clause in it, so I will fully focus myself on Everton. I am very happy at this club.”
