Some reputable sports journalists in Russia stating that Kerzhakov has not been part of Zenit's pre season plans as he is looking at offers from China, Qatar and the A-League. Has stated in the past that Australia is one of the countries he dreams of visiting.

Great player, would be very lethal in the A-League. Only question is what A-League side(s?) have shown interest? He has a lot of money in the bank unlikely to be chasing money.
