Everton manager Roberto Martinez is reported to be tracking Dundee United youngsters Andrew Robertson and John Souttar.
The Merseyside outfit have reportedly been scouting the defensive duo, who have impressed in the Scottish Premiership this season.
According to The Mirror, Martinez is keen to watch the pair play in person before deciding whether to launch a bid to sign the Scotland youth internationals.
The Toffees boss will watch Robertson (left-back) and Souttar (centre-back) against Aberdeen on Wednesday.
