Bayer Leverkusen general manager Rudi Voller says no agreement with Chelsea has been struck over Andre Schurrle's sale.
Voller met with Mourinho before the testimonial match for Michael Ballack at Leipzig, and reports in Germany claimed a deal was finally complete.
Voller told Deutsche Presseagentur: "I cannot confirm a transfer agreement.
"Definitely, we have been in touch about it and we (Voller and Mourinho) have talked to each other about it. But there is nothing to reveal.
"There is interest in the services of Andre Schurrle from Chelsea FC, but we will have to keep on waiting the progress of those next few days."
