Borussia Dortmund cannot afford to sign Alvaro Morata from Chelsea as they look to replace Pierre-Emerick Aubameyang.

There had been reports that Christian Pulisic could go to Chelsea as part of a deal for Morata.

"I'd still say that Morata is too expensive," sporting director Michael Zorc said, and added with a smile: "Without knowing the exact sums involved."

Dortmund qualified for the Champions League but they are in the middle of a squad rebuild.
