Having been bumped by Bochum veteran Marcel Maltritz in the 41st minute, Robben took a step forward, but as the ball had moved too far from him, he proceeded to dive theatrically, before being booked for his actions.
“That was stupid. Perhaps it was a penalty, but then I should have fallen earlier,” Robben said, according to ZDF.
“I saw that I could not get the ball. It was stupid. I must not do things like this – and I apologise.”
Despite Robben receiving the yellow card for his actions, the Dutchman was able to provide the winning goal for his team in the final moments of play, allowing Bayern Munich to progress to the quarter-finals.
“Bochum can be proud, they played a class game,” Robben added.
