German prosecutors have accused Leipzig midfielder Naby Keita of submitting a fake driver's license, according to a report in Bild.
Keita, who will move to Liverpool after this season, could face a "six-figure" fine after trying on two occasions to use counterfeit Guinean driving licenses to obtain one in Germany.
"Both documents were identified as complete forgeries," a court official told Bild.
Keita is also being investigated for driving without a license, Bild reported.
Leipzig said they were aware of the matter, though coach Ralph Hasenhuttl said on Saturday he had yet to discuss the issue with the player.
