Bristol Rovers manager Paul Buckle says Gillingham would have to make a significant offer to sign striker Jo Kuffour on a permanent deal.
The on-loan striker has scored five goals in 10 games for the Gills and boss Andy Hessenthaler has made no secret of his desire to keep Kuffour.
But Buckle said Kuffour will not be allowed to leave without a good offer.
He told BBC Radio Bristol: "If the right deal doesn't come up to suit us, then Joe will be returning to us."
Kuffour will be missing from the Gillingham line-up when they face his parent club this Saturday but Gills boss Andy Hessenthaler says he wants to sign the 30-year-old in January.
"We know about Jo Kuffour, we would like him to stay and that is the one we will be working on if possible," Hessenthaler told BBC Radio Kent.
However, Buckle insists an agreement for Kuffour has not yet been reached.
"He's a Bristol Rovers player, make no bones about that," he added.
"Jo will be going nowhere unless we get the right offer."
