Chelsea defender Filipe Luis does not want to leave the club this summer.
Chelsea left-back Filipe Luis insists he does not want to leave the club despite struggling to earn a starting place.
The 27-year-old, who made seven appearances for the Hornets between 2010 and 2012, will provide competition for fellow keepers Heurelho Gomes and Jonathan Bond at Vicarage Road.
Gilmartin initially joined Watford from Walsall and has also had spells with Yeovil, Crawley and Plymouth.
He has spent the last year at Irish club St Patrick's Athletic.
