Musa is staying with his English grandparents while he and his agent look to get him trials, hoping to capitalise on his Premier League club experience and status as an international player.
"He's got Fulham's support. That's the situation we're in because their season's in-between at the moment," said Mandy Musa.
"He's got every potential to do well. Something will come along."
Coming into the next English season there could be room on the books of a club in the Football League Championship or the next tier of Football League's 1-2.
There has been speculation back home that the Wellington Phoenix could be interested in their former player with new coach Ernie Merrick having room for five more players on the roster.
Mandy Musa said they have not ruled out a return to the A-League for either the New Zealand franchise or one in Australia.
"He possibly would if that was on offer but we haven't heard anything."
