The Australia international has been without a club since leaving Alaves and can sign outside of the transfer window.
Nurnberg had been progressing in talks with Aloisi but the 31-year-old, according to his Sydney-based manager, would prefer a return to England after previously representing Coventry City and Portsmouth.
"We are just waiting for contract details and what sort of package is on offer," said agent Paddy Dominguez.
