Everton have made an enquiry for Crystal Palace winger Yannick Bolasie, who is valued at around £30m.
Ronald Koeman is keen to bolster his Everton squad with new additions and is targeting the Congolese international.
Bolasie has gradually developed a reputation as a Premier League proven attacker but has only scored nine goals in 89 appearances for the Eagles in the top-flight.
But the pacey attacker is rated highly by the Crystal Palace hierarchy, who are keen to ward off interest from Koeman's men by placing a hefty price tag on their coveted asset.
