The whole six penalties and a 39th place on Tuesday.
No wonder the Swedish star has been walking around and sulking.
On Friday in the sprint over 10 kilometers, he was himself again.
I was disappointed with the previous race, now I'm satisfied with how I performed the day. After such a bad race, you want to deliver, says Samuelsson and adds:
I hope I get peace and quiet with myself and can have fun ahead.
"Rode hard"
Samuelsson had a penalty in the sprint in Finnish Kontiolahti.
It cost him the victory. French winner Emilien Jacquelin, France, shot full and won with a 18.9-second margin.
I rode hard from the start. Was a bit cowardly towards the wall, on both laps, I lost time there, but it was probably right. I did well on the shooting. Then on the sprint lap, it went very fast, hurt my body, says Samuelsson when describing the competition.
First in three years
For the Frenchman, it was the first victory in three years. During that time, he has had problems and says himself that he almost burned out.
In three years, too much has happened. It feels like I found my way back to aggression and the will to win, says Jacquelin.
German Philipp Nawrath finished third, he shot full but was still over six seconds behind Samuelsson.
So no Norwegian managed to reach the podium. Star Johannes Thingnes Bø finished fifth, and then four more Norwegian skiers followed in the places directly after.
If Sebastian Samuelsson took a brutal revenge, it went heavier for most other Swedes.
Martin Ponsiluoma had three penalties on 27th place, 1.29 behind the Frenchman.
No, I'm really not satisfied. The two last standing bother me really, lying is stable with one penalty, says Ponsiluoma.
Malte Stefansson finished 34th, Viktor Brandt 41st, and Jesper Nelin 44th.
