Watford have no interest in selling striker Troy Deeney this summer, Sky sources understand.
Cardiff are understood to have cooled their interest in the 30-year-old following an initial inquiry.
Sources have told Sky Sports News that Deeney is seen as a key player in Javi Gracia's squad at Vicarage Road this season as they look to improve on their 14th place finish last season.
The Hornets - who have have already sold Richarlison to Everton for £40m during the summer transfer window - begin the new campaign at home to Brighton on August 11.
