Bayer Leverkusen hope to persuade Chelsea winger Kevin de Bruyne to join them as part of Andre Schurrle's move to Stamford Bridge.
The Daily Mail says after impressing on loan at Werder Bremen this season, De Bruyne is in demand in the Bundesliga, with Leverkusen, Borussia Dortmund and Schalke all vying for his services.
Dortmund have even indicated a willingness to buy him outright for £15million, but Chelsea are thought to favour Leverkusen's proposal of taking him on loan next season as a temporary replacement for Schurrle.
With De Bruyne aware of Dortmund's intentions, there could yet be some hard bargaining before a deal for Schurrle is concluded to everyone's satisfaction.
