The Curacao international could follow his former Saints boss to Goodison Park, a report claims.

Koeman brought Maarten Stekelenburg to Goodison Park earlier this month, having signed his fellow Dutchman on loan for the Saints a year ago.
And the 53-year-old is now set to raid St. Mary’s for right-back Cuco Martina, according to the Sun.

Everton are in need of more bodies in Martina’s position, having released Tony Hibbert earlier this summer.
Besides first choice Seamus Coleman, the Toffees have youngsters Jonjoe Kenny, Tyias Browning and Mason Holgate.
New Southampton boss Claude Puel will reportedly allow Martina to leave as he favours more attack-minded full-backs.
And the report claims Puel could make another move for Jeremy Pied as the Curacao international’s replacement, after his former Nice colleague snubbed Saints’ initial offer.

The 27-year-old, who can also play on either wing, is said to be holding out for more money.
Everton have been also been linked with St. Mary’s stars Fraser Forster, Virgil van Dijk (both Record) and Dusan Tadic (Sun), as well as the now departed Graziano Pelle (Star) and Victor Wanyama (Record).
Could more Saints stars follow Koeman?
