De Bruyne joined Chelsea from Genk two years ago but has only started two Premier League games and has been sent out on loan to Genk and Werder Bremen.
The Belgium midfielder's agent Patrick De Koster met with Chelsea officials last week and revealed that his client wants to leave Stamford Bridge.
De Koster claims Juventus and Atletico Madrid have shown interest in De Bruyne, but said the player wants to return to Germany, with Wolfsburg being his preferred option.
"Another loan wouldn't be good for the player or the club," De Koster told Press Association Sport.
"The player and his family would like to secure a permanent solution because he has been out on loan already twice.
"It's a World Cup year and for this reason he needs to play.
"Now in the next few hours or days, we will see if somebody finds an agreement with Chelsea. If there is an agreement I will speak with the player about what we will do.
"His preference is to go back to the Bundesliga. There have been discussions with Wolfsburg and other clubs."
