Released by Olympique Marseille earlier this season after attacking a supporter, Evra has been a free agent for over two months.
Fanatik says Gala coach Fatih Terim has approved them making an offer to the fullback.
Evra has been informed he will be signed if Gala cannot find a younger left-back signing over the next month. The deal will be to the end of this season.
For his part, Evra has insisted he isn't ready to hang up the boots after his controversial departure from OM.
