Neureuther beat Austrian Manfred Pranger into second place and Swede Andre Myhrer into third on Saturday.
Yet despite Neureuther's slalom victory, the complicated nature of skiing World Cup titles means that Austria's Reinfried Herbst took the World Cup slalom title and Switzerland's Carlo Janka took the overall 2010 World Cup title after winning the men's giant slalom on Friday.
Neureuther's final time over the race's two legs was 1min 43.63 sec, with Pranger 0.29 sec, and Myhrer 0.35 sec behind him.
“I simply felt really good today,” Neureuther said.
This is a huge turnaround for the 25-year-old who failed to perform well at the Olympics and had considered giving up his slalom career.
He said, “There was much which did not go as I had imagined. It is fabulous to be compensated for that like this. At first one does not want to believe in it, but then it went like a dream.”
His father Christian was there to see his son win at the same spot as he had in 1974. He told ZDF television, “That is a very special family story.”
