Real Madrid took the lead after Ronaldo fed the ball into the box and it eventually found its way to Mayoral at the back post. The striker chipped over the keeper and Madrid were in front.
With Dortmund unable to get a touch of the ball, Kovacic's cross fell for Ronaldo outside the edge of the area. The Portuguese striker took one touch and sent a wonderful shot flying into the net.
Burki was rooted to the spot as Ronaldo wheeled away in celebration of yet another Champions League goal to his name. With that goal, Ronaldo became the first player to score in all six games of a Champions League group stage campaign.
6 - Cristiano Ronaldo is the first player to ever score in each of the six games of a #UCL group round (nine goals). Infallible. pic.twitter.com/yVuf3HVs70
