The Portugal international is Madrid's regular penalty-taker and scored from the spot in injury-time to complete his hat-trick, but for the first kick it was, rather surprisingly, defender Ramos who stepped up.
Ramos duly slotted his penalty into the top corner to put Madrid 3-1 up, and Ronaldo said afterwards: "Sergio told me to leave it to him and I'm not going to argue with him over a penalty. He's my team-mate and a great friend. The goal will help Sergio gain more confidence."
Ramos said of the incident in AS: "On the pitch everyone was surprised. There's usually an order, but I was confident and had a thorn in my side because I hadn't scored and normally I have a decent goal average.
"I hope this is the start of a good run."
