Watford are weighing up a move for former Dagenham and Redbridge goalkeeper Chris Lewington, Sky Sports understands.
Lewington is a free agent after seeing out his contract with the League Two club earlier this summer.
The 25-year-old is highly-regarded after impressing during his time at Victoria Road, making over 100 appearances for the Daggers.
A number of Championship and League One sides are thought to be keeping tabs on Lewington's situation, with the custodian an attractive option on a free transfer.
Watford are thought to be ready to invite Lewington to Vicarage Road for pre-season training as they look to cast an eye over the keeper before deciding whether to offer him a move to the club.
