"It was an unbelievable feeling," Eller said of the goal, a rebound at 12:23 of the third period while standing behind Golden Knights goalie Marc-Andre Fleury.
"It was almost too good to be true. I was trying to get to the rebound. Fleury was so far out I couldn't get in front of him, so I got behind him, and that's where the puck comes.
"It's like you get to write the best story in the world yourself, score the game-winner in the Stanley Cup Final. I don't know how it can get better than that. We played right to the last second. It was a battle all the way through, just like it's supposed to be."
It was pressing 5 a.m. Friday in Denmark when Eller scored the goal that would make history, the 29-year-old becoming the first Stanley Cup champion from his country.
He knew the game was being shown in a rented movie theater in Rodovre, but he had no idea how many were in the seats when he scored his seventh goal of the postseason, lifting the Capitals to their first championship.
