The victory in the classic Liège-Bastogne-Liège came on Sunday for Primoz Roglic.
The Slovenian from Jumbo-Visma had to leave the Tour victory to his fellow countryman Tadej Pogacar in extremis two weeks ago.
"I finally managed to win some", Roglic said modestly after beating Julian Alaphilippe in the sprint.
The world champion raised his hands too early, but was also put back to fifth place due to the hindrance of Marc Hirschi.
"It is unbelievable that it worked. I have always believed in it and fought to the last centimeter. This gives a wonderful feeling."
Although Roglic has the overall victory in the Tour of Spain and Tirreno-Adriatico on his honors list, Liège-Bastogne-Liège means his first major victory in a one-day race.
He is also the first Slovenian to win a monumental classic.
"Winning a monument was on my wish list, so it's great that it worked out", said the 30-year-old Slovenian, who thanked his teammate Tom Dumoulin extensively.
The Dutchman took the lead on the last climb.
"Tom did very well in the end, he did a great job. The whole team was fantastic today."
