Wolfsburg forced Real Madrid’s collective backs against the wall and is 90-plus minutes away from one of the biggest upsets in UEFA Champions League history.

Wolfsburg carries a 2-0 advantage into the second leg of its Champions League quarterfinal series with Real Madrid, thanks to last week’s stunning victory. The teams play again Tuesday at the Santiago Bernabeu Stadium in Madrid in the decisive leg.

Real Madrid is in scintillating form at home, having scored 17 goals and conceded only once in its last four outings at the Bernabeu. Cristiano Ronaldo, the Champions League’s all-time leading scorer, must be at his best in what could be his final game for Real Madrid in the competition.

Wolfsburg never has progressed this far in the Champions League, and the German side must deliver another dogged performance in order to prolong its fairy-tale run.

Here’s how to watch Real Madrid vs. Wolfsburg online.
