Chelsea youngster Kevin De Bruyne is wanted by Bayer Leverkusen, according to reports in Germany.
The Blues landed De Bruyne in January 2012 as part of a recruitment drive for the best young Belgians which also included Romelu Lukaku, Eden Hazard and Thibaut Courtois.
But £6.7m man De Bruyne is yet to feature for Chelsea, having spent the second half of last season on loan at Genk as part of the deal - and then joining Werder Bremen on a season-long spell in the summer.
The 21-year-old has impressed in the Bundesliga, making 26 appearances and netting six goals for the struggling side which has attracted the interest of Leverkusen.
Club CEO Wolfgang Holzhauser described De Bruyne as a 'very interesting man' in an interview with the local newspaper Kolner Express, and now Bild claim Leverkusen are lining up a summer offer for the 21-year-old Belgium international.
Interim Chelsea manager Rafa Benitez will leave in the summer so it will be up to the incoming boss to decide whether De Bruyne will be integrated into the first-team squad during the summer.
One option is another season-long loan spell, to ensure the midfielder - under contract until 2017 - continues to play first-team football.
But Bayer will attempt to land him on a permanent basis and think they could tempt Chelsea to sell by perhaps offering Andre Schurrle as part of the deal.
The 22-year-old has been a long-term target for the Blues and it has been reported that they had a £20m offer rejected last summer.
