Borussia Dortmund are said to be close to agreeing a deal for Blackburn Rovers transfer target Robert Lewandowski.
The Polish striker has been linked with Sam Allardyce's team but Dortmund have reportedly come to a verbal agreement to sign the player.
Dortmund manager Michael Zorc has admitted he will have to sell players before he can bring in fresh faces for the new campaign - although a clearout is underway to allow the Lech Poznan front man to arrive at Signal Iduna Park.
Zorc told German newspaper Bild: "(Robert) Lewandowski has verbally assured he wants to play for Borussia Dortmund next season.
"We are just able to buy after selling players, but I am not making any particular comment on names.
"It's a fact that the squad will be looking different next season."
A £4million fee is reportedly being lined up for the 21-year-old as Die Borussen prepare to let Nelson Valdez, Dimitar Rangelov and Tamas Hajnal exit the club.
Florian Kringe is also believed to have no future at Zorc's team, with the midfielder currently out on loan at Bundesliga rivals Hertha Berlin.
