Chelsea are believed to have spent around £7 million acquiring the services of Kevin De Bruyne back in January 2012.
They allowed him to see out that season with former employers Genk, before sending him on loan to Werder Bremen in the following campaign.
De Bruyne impressed in the Bundesliga and was expected to play more of a prominent role at Stamford Bridge upon his return to England.
The 23-year-old winger has caught the eye again in familiar surroundings, producing six goals and 12 assists in all competitions this term.
Those efforts have sparked talk of a January switch to either Manchester City or Bayern Munich, with both clubs reportedly ready to pay £18 million for the Belgium international.
Wolfsburg have no intention of selling, though, and De Bruyne’s agent has sought to bring an end to the unsettling transfer talk.
Patrick De Koster told Sport1: "There's been no contact with Bayern at all and no contact with any other club either. Kevin has played a great season so far with Wolfsburg and it's only normal that other clubs are watching him, but nobody has spoken to me.
"I have great respect for Wolfsburg and I thank (director of sport) Klaus Allofs for giving Kevin the chance when he was not in a good situation with Chelsea and could not play.
"We can only thank Wolfsburg. He signed a new contract until 2019 with them in January and after a good World Cup, he's been in good form for Wolfsburg. Naturally he is only thinking about Wolfsburg. Kevin only wants to stay here."
Chelsea took the decision to move De Bruyne on as they already have the likes of Willian, Oscar, Eden Hazard and Andre Schurrle on their books.
He is, however, a top-level performer and one that could come back to haunt the Blues at some stage in the future.
If he can maintain his current standards, interest in his services will intensify and leading clubs in England will be expected to lead the chase for his signature.
