The midfielder struck with ten minutes left of the home match in the Champions League. With the goal, he secured three important points in the Belgian club Club Brugge's pursuit of continued play in the European cup.
Then Casper Nielsen talked about the tough time off the pitch. In October, the Dane and his partner lost their second child, who was born only five months into the pregnancy.
"On October 15, our beautiful little brother was born, and now heaven is his home. It's heartbreaking to think that we can't take him home. He will always be a part of our family", wrote Marie Kuhlman Andersen on Instagram.
After the CL win, Nielsen talked about the tough months.
It's been a very tough time, but hopefully this is a step forward, he said to Viaplay.
I'm trying to put it behind me. It's something that I and my family have to live with. I've had fantastic support from home, and it helps me.
