Chelsea boss Mauricio Pochettino has made a move for Southampton midfielder Romeo Lavia.
Football.London says Pochettino has put in a call to former club Saints for Lavia.
The Belgian is expected to be on the move this summer after Southampton's relegation.
Southampton are reluctant to sell, though will consider parting with Lavia for 50m.
Chelsea failed with attempts for Lavia over the past two transfer windows and are now ready to try again.
