Chelsea midfielder Kevin De Bruyne is not interested in another loan spell away from the club as he eyes a permanent move this January back to Germany, according to his agent.
The Belgian international has failed to feature in a Premier League game for the club since late September and is almost certain to leave Stamford Bridge this winter having struggled to find a role within Chelsea's burgeoning attacking midfield options.
Bayer Leverkusen and Wolfsburg are keen to bring the 22-year-old back to the Bundesliga where he excelled on loan for Werder Bremen last season, while Atletico Madrid and Juventus have both been credited with keen interest.
Chelsea have reportedly told clubs they must pay £25m to sign De Bruyne with a permanent move away looking increasingly, as the player's agent underlines his client's intentions to return to the Bundesliga.
"A loan would not be good for the club or the player," De Koster was quoted as saying by Bold. "The player and his family would therefore like a permanent solution, as he has already been loaned twice.
"It's a World Cup year and therefore he should be playing."
"Over the next few hours or days we will get to see if there is someone who reaches an agreement with Chelsea.
"If that happens, I'll talk with the player about what we should do. He wants to return to the Bundesliga. There have been talks with Wolfsburg and other clubs."
After signing for the Blues in January 2012, De Bruyne was allowed to finish the remainder of the season with Belgian outfit Genk, before moving to London. It was a temporary stay, however, as he was quickly snapped up by Werder Bremen for the season, where he enjoyed a terrific campaign and won many admirers in the Bundesliga.
Wolfsburg have not been put off by Chelsea's demands for the midfielder, although they will attempt to drive the Premier League side's asking price down to a figure in the region of £17.5m after the clubs met earlier this week, the Daily Telegraph report.
