Sandro Wieser is a Liechtensteiner professional footballer who plays as a midfielder for Swiss Challenge League club Vaduz and the Liechtenstein national team.

The Liechtenstein national football team is the national football team of the Principality of Liechtenstein and is controlled by the Liechtenstein Football Association. The organisation is known as the Liechtensteiner Fussballverband in German. The team's first match was an unofficial match against Malta in Seoul, a 1–1 draw in 1981. Their first official match came two years later, a 0–1 defeat from Switzerland. Liechtenstein's largest win, a 4–0 win over Luxembourg in a 2006 FIFA World Cup qualifier on 13 October 2004, was both its first ever away win and its first win in any FIFA World Cup qualifier. Conversely, Liechtenstein is the only country that lost an official match against San Marino, albeit in a friendly match. Liechtenstein suffered its biggest ever loss in 1996, during qualification for the 1998 FIFA World Cup, losing 1–11 to Macedonia, the result also being Macedonia's largest ever win to date. The team's head coach is currently Konrad Fünfstück.
