After accidentally ignoring the ball boy's request for a handshake at the Volksparkstadion before proceedings got under way, Stindl took to Twitter after his side's triumph to announce that he was giving his matchworn shirt to the bypassed ball boy by way of apology.
This is what Stindl himself had to say in the tweet below: "Sorry, I'm always so nervous before such a big game!"
Sorry!! Bin auch immer noch nervös vor so einem Spiel! 😬 https://t.co/5y8OZLnE0d— Lars Stindl (@stindl28) March 1, 2017
And here was the scene itself in all its 'glory'...
Of course, Stindl's mood was no doubt helped by the fact that his goal paved the way for a Gladbach win - the first time the club have reached the DFB Cup semi-finals since 2011/12. It was the club captain's eighth goal in as many games.
The Foals will face Eintracht Frankfurt at home in the semi-finals, while Borussia Dortmund or Sportfreunde Lotte will travel to Bayern Munich.
