Borussia Dortmund captain Marcel Schmelzer says Pierre-Emerick Aubameyang celebrating his goal against Schalke with a Nike mask was a “stupid” thing to do.
The Gabon striker scored the opener against Schalke last weekend, but his celebration didn’t go down well with Dortmund’s kit sponsor, Puma.
Hans-Joachim Watzke also planned to give Aubameyang a firm talking to for his actions.
“We already thought he would come up with something for the derby,” Schmelzer told Sky.
“But what he did was stupid. None of the players knew that was coming.
“We have already had a word with him, the club will also have another chat with him and resolve the situation internally. Auba knows what the deal is.
“We know what he can do for us and he knows what we can do for him. The important thing is that we keep acting as a team. Auba is well aware of this and that is the most important thing.”
