The Belgian spent two years as a Blues player before leaving the club in January 2014.
Despite this spell, he was only truly a Stamford Bridge star for the six months before his exit, with loan spells at Genk and Werder Bremen having taken up the majority of his time at Chelsea.
Since his move away from Jose Mourinho’s side, De Bruyne has flourished, and is now considered to be one of the Bundesliga’s finest talents.
14 goals and 21 assists in all competitions so far this term are statistics that have alerted a host of top clubs, with Manchester United in the mix.
However, Schafer believes that his 23-year-old tam-mate is ready to stay where he is:
“I think that our chances [of keeping De Bruyne] are really good,” he is quoted by the London Evening Standard.
“He has already experienced not getting so much time on the field at Chelsea, which is top club in Europe.
“And that is why I think the best thing for him would be to stay for minimum one more year at Wolfsburg.
“Next year he could play Champions League here and win titles with us.
“If you want to win titles you need extraordinary players. And you really have to say that Kevin De Bruyne is at the moment the best player in the Bundesliga not only because of his stats.
“You can see that in every single game. And we’re really, really happy to have him and to keep him till the next season or maybe a little bit longer.”
