Wolfsburg stunned an out-of-sorts Real Madrid by comfortably beating the Spaniards in the first leg of their Champions League quarter-final tie.
The hosts were awarded a controversial penalty when Casemiro was deemed to have fouled Andre Schurrle. Ricardo Rodriguez converted from the spot.
Real were poor defensively and a rapid attack ended with Bruno Henrique setting up Max Arnold for the second.
Wolfsburg could have scored more while Real had few clear chances.
