The 21-year-old De Bruyne has been a regular fixture at Werder Bremen this term, scoring six goals in 29 Bundesliga appearances and has reportedly commanded the interest of Bayer Leverkusen, Borussia Dortmund and Schalke.
German daily newspaper Welt claims Leverkusen forward Andre Schurrle has agreed to join Chelsea this summer on a five-year contract, but the German club is stalling the deal as it also reportedly wants De Bruyne included in the package.
"Chelsea does not want to sell Kevin. They want to send him out on loan again." Patrick de Koster told Welt. "Several clubs from Bundesliga are interested in him such as Leverkusen, Dortmund and Schalke.
"Bayer Leverkusen is a very good option. They will play in the Champions League next season and Kevin could probably play in Andre Schurrle's position.
"Kevin wants to proceed in his career, and Leverkusen might be the right place."
