Barcelona have reached agreement with Borussia Dortmund on a transfer of Ousmane Dembele.
The deal could reach €150 million ($177 million) in total for Dortmund.
Asked about L'Equipe's report by Sky Germany, Watzke said: "I can't confirm it. We will not make any comments.
"A lot of nonsense has been written by L'Equipe in recent weeks. We would also not comment on this [if there had already been a meeting between BVB and Barcelona]. We'll see them at the draw."
Dortmund previously rejected Barcelona's offers for Dembele.
Dembele was bought by Dortmund last year from Rennes for €15 million.
