Thomas Tuchel thinks fans will remember Pierre-Emerick Aubameyang's latest mask stunt for Dortmund will be remembered for years to come.

Borussia Dortmund striker Pierre-Emerick Aubameyang could have some explaining to do over the celebratory mask he donned during the 1-1 Revierderby draw at Schalke.

Aubameyang gave Dortmund a 53rd-minute lead at the Veltins Arena and reverted to his famed celebration, having previously worn Batman and Spider-Man superhero masks.

He did not pay tribute to any caped crusaders on this occasion, with the mask resembling one depicted during a recent advertising campaign for his boot sponsor Nike.

Dortmund's kit manufacturer is rival sportswear firm Puma and the forward, who has a stunning 24 goals from as many Bundesliga outings this season, could now face a tricky conversation with club chief executive Hans-Joachim Watzke.

Speaking about the mask after the game, Watzke said: "I can't verify it yet. But if it was an advertisement partner we will talk with him and it will be difficult for him."

Commercial sensibilities aside, Dortmund head coach Thomas Tuchel enjoyed a memorable moment of exuberance from his star man and dismissed suggestions the stunt was egotistical.

"There is nothing arrogant about Aubameyang's masked goal celebration," he said.

"It's a derby and I'm sure you'll be talking about it in years to come."
