Goodison Park outfit chase Nou Camp full-back.
Everton are in talks to sign Barcelona right-back Douglas according to the Metro.
The 24 year old Brazilian only moved to the Nou Camp in August and has made appearances in La Liga and Copa del Rey fixtures this season and a January exit would be something of a surprise.
The former Sao Paulo man joined Barcelona on a five year deal though the Toffees feel they can land the wide-man on an initial loan deal.
Interest in Douglas may lead some to speculate as to the future of Republic of Ireland star Seamus Coleman, who is Martinez’s current first choice option in the spot.
