Werder Bremen are eyeing Everton midfielder Davy Klaassen.
Werder see the Holland international as a replacement for Thomas Delaney, who has moved to Borussia Dortmund.
Klaassen is rated at €13-14m by Everton, though Werder are keen for the Blues to drop their valuation.
However, intermediaries have pointed out to Werder they raised €20m from the sale of Delaney this summer.
Klaassen, who joined Everton last summer from Ajax, is available from Everton after a disappointing 12 months in England.
