Watford have been watching teenage Toulouse goalkeeper Albon Lafont, according to reports in France.
Arsenal, Porto and Juventus are also said to be monitoring the progress of the 17-year-old custodian, who has been tipped to go on to big things in the future.
L'Equipe claim Watford have recently sent their talent spotters to France to watch Lafont as he performs on a regular basis in Ligue 1.
Toulouse have him under contract until June 2020, but club officials believe his progress to the first team merits a salary increase and both parties are currently in discussions over a new contract.
Last season Lafont made a total of 24 appearances for Toulouse, keeping eight clean sheets.
