Schalke have rejected reports that they have already agreed a deal to sell goalkeeper Manuel Neuer to Bayern Munich.
Neuer, 25, is understood to be close to a switch to the Allianz Arena, making the move between the two German clubs despite strong interest from Manchester United earlier in the year.
Bayern are thought to have had a £22million bid accepted for Neuer, but Champions League semi-finalists Schalke deny that he is definitely leaving the club.
Club executive Peter Peters told Sportinformationsdienst: "We had good talks with Bayern Munich and we also reached an idea about the economic part of an agreement.
"But we have not yet decided to accept the offer. Manuel Neuer is under contract at Schalke until June 2012, he is our first-team goalkeeper and we really feel he is an important player of our first team."
Premier League champions United are now poised to complete a deal for Atletico Madrid goalkeeper David De Gea, clearing the way for Bayern to secure the services of Neuer.
