Everton defender Johnny Heitinga says he's aware of interest from Manchester City.

Heitinga penned a long-term contract upon his arrival on Merseyside in 2009 and insists he has no intention of breaking that agreement any time soon.

"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."

Heitinga is currently away with the Dutch national side preparing for this summer's World Cup finals.
