Watford are eyeing Arsenal attacker Theo Walcott for a January deal.

The Daily Express says Watford are aiming to strengthen in January with their form recently tailing off and Walcott is on their radar.

The England international has struggled this season, with Arsene Wenger regularly overlooking him.

Yet Watford, though interested, have their doubts.

Silva is understood to be concerned by the player's attitude and whether he has the drive to succeed at Vicarage Road.

West Ham are also monitoring Walcott's situation at London Colney.
