Recent reports suggested that the 21 year-old was on the verge of joining the Trotters after a bid of £350,000 was accepted by A-League champions Central Coast Mariners.
Although Freedman admitted he is keeping a close eye on Sainsbury, no formal offer has been put forward to sign the talented youngster.
"There's been an enquiry to see what he's doing over the summer. Obviously he's finished his season and there's an enquiry with my contacts over in Australia if he's going to go lie on the beach or if he wants to have a fly over and have a look around the training ground," he told Tower FM.
"Maybe have a fitness test and see if he's the kind of guy I would find in my program.
"That enquiry has obviously been leaked out there as an approach and a bid and things like that which has never been the case."
Sainsbury, who was voted into the A-League's Team of the Year after an outstanding season for the Mariners, is also reportedly a target for Southampton.
