Everton are eyeing West Bromwich Albion fullback Cristian Gamboa.
The Daily Mail says Everton are showing an interest in West Brom right back Gamboa as they look for cover for Seamus Coleman.
Former Wigan manager Martinez is aware of interest from Manchester United in Coleman but has no intention of selling.
Gamboa, a Costa Rica international, joined West Brom last summer for £2million from Norwegian side Rosenborg.
