The Romania international has been linked with City in recent weeks.
"I have a very good relationship with the City officials," Victor Becali told prosport.ro.
"The boy is very appreciated by the manager and the staff. The idea is to have him play in the centre of the defence, next to [Matija] Nastasic. However, Claudio Lotito [Lazio president] asks 16-17 million euros for him."
