A move to France was on the cards next for Geiger, as he signed for AS Saint-Étienne during the Summer of 1988. He was a big hit and a first-team regular at Stade Geoffroy-Guichard, but opted for a return to Switzerland and Sion, in 1990. During his second spell, he saw the form of his life as he became captain for both club and the country. He lifted the league trophy for the fourth time in his career as Sion were crowned champions in 1991–92.
