The Daily Mail says the Dutch international has one year left on contract and is in a strong position.
City's offer of a new deal has fallen short of what he is after and he wants more time on the pitch. That is unlikely to change but he is happy to see out his contract and leave for free next summer if he doesn't get what he wants. The interest from Bayern Munich could prove ideal for all parties if the Germans put forward an offer suitable to City.
They paid £18m for the 27-year-old in 2009 and want around half of that. Bayern are likely to offer around £6million and kick-off some negotiating.
