Newcastle have joined the list of clubs showing interest in Lyon right-back Malo Gusto.
The 19-year-old is wanted by Manchester United also but bids are expected to be shelved until the summer with Lyon asking for at least £35m for January.
The defender, who has played for France at various age-group levels, is one of the club's most prized assets and has been a valuable player this season.
He shares dual citizenship between France and Portugal, and played against both Rangers and West Ham in the Europa League last season.
