Borussia Dortmund are adamant Robert Lewandowski will not be sold to Bayern Munich.
Bayern are regarded as favourites for the Pole, who has also been linked with Manchester United.
"We have communicated to the player and his advisers that we will not agree to a transfer to FC Bayern this summer," BVB chief Michael Zorc told Kicker.
"There will be with him now perhaps a small phase of disappointment," added Zorc. "But then he will deliver his usual performance, as does a professional with character... and Robert has a whole lot of character."
