General manager Pep Segura claimed in the wake of those defeats that Barcelona were on the verge of capturing not only Dembele but also Liverpool star Philippe Coutinho, another whom they have keenly pursued this summer.
The Catalans are desperate to reinvest following Neymar's world record £198million move to Paris Saint-Germain and have identified the pair as ideal replacements.
"Barcelona have not managed to fulfil their wish to complete Dembele's transfer - until now, they aren't one millimetre closer", Watzke told German magazine Kicker.
"I don't know what will happen, we have to be patient for a few more days".
Dembele joined Dortmund from Rennes in July 2016 and made 32 appearances in the Bundesliga, scoring six times.
Ousmane Dembele had an average shot accuracy of 48% in the Bundesliga last season
On Saturday, the striker scored a hat trick in the 4-0 DFB Pokal win over Rielasingen-Arlen.
Dortmund's tough-tackling defender Sokratis Papastathopoulos says Dembele should follow the example of Aubameyang, who has been linked to a big-money move to China but has been told that he is staying.
"Everyone has to be clear that he must work for the team and fall in line".
Dembele will be hoping that Klopp goes easy on him, or he may be running for his life sometime soon as Jurgen is no man to mess with.
The Catalans find themselves urgently needing to replace Neymar, who left for PSG in a sensational €222m switch early this month. We'll see after that.
"It appears Ousmane does not want that".
