Paartalu would be a good recruit for Roly's spot if Roly's money can be used for that. And there is no visa spot required.
When in 2014 Newcastle Jets were chasing him after his stint in Korea ended, he apparently said publicly "I want to be at a club with an ambition to be successful on/off the field and Melbourne City FC is that club" which probably would not have made him any friends in Newcastle.
On the strength of that, I would say he'd turn us down, money or not.
