Borussia Dortmund's director of sport Michael Zorc claims De Bruyne wants to join his side and not their Bundesliga rivals.
Germany international Schurrle is already believed by Leverkusen's general manager Wolfgang Holzhauser to have agreed terms with Chelsea.
Holzhauser also recently claimed an agreement had been reached between both clubs which would see De Bruyne, who spent the season on loan at Werder Bremen, moving in the opposite direction on a one-year loan deal.
Dortmund are also keen on the Belgian, however, and Zorc believes the player would rather wear their colours next season, thus jeopardising Schurrle's move to Chelsea.
"De Bruyne only wants to come to us," he told Germany's Kicker magazine.
Dortmund are keen on signing 21-year-old De Bruyne in a permanent transfer, although Chelsea appear reluctant to let him go and may prefer the loan option, which would favour Leverkusen.
