Video: Barcelona international has nightmare howler to cost Euro giants in friendly shock

Could Marc-Andre ter Stegen replace David de Gea at Manchester United?

Barcelona goalkeeper Marc-Andre Ter Stegen had an absolute disaster on Sunday when his glaring error helped Germany on their way to a surprise defeat against Slovakia.

The two European Championship contenders met in Augsburg, as Joachin Low looked to assess some of his peripheral options ahead of the upcoming continental showpiece in France.

Mario Gomez fired Germany into the lead inside the opening 15 minutes, but Germany capitulated and goals from Marek Hamsik and Michal Duris turned he tie on its head.

Slovakia sealed their victory in the 52nd minute, when the hapless Ter Stegen let a week shot from Juraj Kucka through his legs.

The stopper was introduced at half time, but his slim chance of unseating Manuel Neuer ahead of the Euros appears to have ended with this miserable blunder.
