Ajax midfielder Davy Klaassen is being tracked by Everton.
The Sunday Mirror says Everton boss Ronald Koeman is keen on Klaassen.
The 24-year-old Netherlands international — set to be out of contract in 2019 — has been heavily scouted by the Goodison Park giants' Dutch gaffer, who must now wait to see if the Amsterdam side are willing to sell.
Italian side Napoli and Germany's Eintracht Frankfurt are also in the race to sign Klaassen.
