Barcelona, Manchester United and Liverpool have reportedly set their sights on youngster Joao Pedro.
The 17-year-old has already agreed to link up with Watford, although age restrictions are preventing a switch going through until 2020.
However, it appears that the Hornets face a battle to keep hold of the teenager due to his form while representing Fluminense.
The Daily Mail cites Spanish sources as saying that Barca are confident of securing the signature of the Brazilian in the coming months.
Man United and Liverpool are also said to be monitoring the situation ahead of Pedro's scheduled arrival at Vicarage Road in January.
