Everton boss Ronald Koeman must act quickly if he is to sign Ajax midfielder Davy Klaassen.

De Telegraaf says Klaassen's future could soon be decided with AS Roma approaching Ajax.

Ajax are ready to sell and are seeking €25-30 million for their club captain.

Roma have opened formal talks, though are unlikely to get a clear run with Koeman also keen.

Klaassen, tied to Ajax until 2019, has played 180 games for the Dutch giants.
