Everton are chasing Dundee United and Scotland Under-21 defender Mark Wilson, BBC Sport understands.
Mark Wilson has scored four times this season
It is believed that Everton manager Davie Moyes has approached the Scottish Premier League outfit about the player's availability.
The 20-year-old has already made 83 appearances for United and this season has chipped in with four goals.
He was controversially red-carded a fortnight ago for a hand ball, when TV footage showed it was a header.
