West Ham are chasing Watford youngster Dion Pereira.
The London Evening Standard says the Hammers and Newcastle United are moving for the teen.
Pereira was named the club's young player of the year at Monday's awards ceremony at Wembley, yet his future is uncertain. Pereira first played for Watford at Under-9 level but is weighing up his future.
The 18-year-old broke into the Watford first-team squad this season, coming on as a substitute in the matches against Leicester and Manchester City in May – though he has yet to sign a professional deal with the Hornets.
Pereira, a left-footed wide player, has been offered terms by Watford but is considering his options.
