Winterthur

The club was founded in 1896 by students of the local school of engineering and following a fusion with two local teams, it was called Vereinigte Fussballclubs Winterthur between 1929 and 1946. They enjoyed their best success in the early part of the 20th century winning the Swiss Championship three times (in 1906, 1908 and 1917), before consecutive relegations in 1931 and 1934. They played in the lower leagues until regaining promotion to the Nationalliga B in 1950. They have since stayed in the second division for most of their history, except for several appearances in the Nationalliga A, from where they were most recently relegated in 1978 following a promotion ten years prior. Notable managers from this period include Gabet Chapuisat, Wolfgang Frank, René Hüssy, Timo Konietzka, and Willy Sommer

They famously lost to West Auckland F.C., an English amateur team in what is thought to be the first international football club competition, the Sir Thomas Lipton Trophy. The club have also reached the final of the Swiss League Cup in 1972 and 1973 and Swiss Cup in 1968 and 1975, however lost on every occasion.

In 2005–06 season the club finished 14th place in the Challenge League. Despite performing poorly in the league, they made it to the semi-finals of the Swiss Cup by defeating Grasshoppers, Lucerne and Servette, before losing to eventual winners Sion at home.

In the 2021–22 season, Winterthur were able to achieve a last round championship victory in the Swiss Challenge League, to gain their first promotion to the Swiss Super League. It will be the first time since 1982 that the team played in the top Swiss football league. It is their fourth victory in the second Swiss football league. Following their promotion, coach Alex Frei, who led the team during this successful season, departed the team to join FC Basel, along with assistant coach Davide Callà. They're replaced by Bruno Berner and Aurélien Mioch.

Due to the expansion of the Super League for the 2023–24 season, there would be no direct relegation in Winterthur's first season back in the top flight, as the last placed team would advance to the relegation playoff. The goal for the season therefore was clear: avoid the relegation and secure a spot in the Super League for the next year. This still proved to be a difficult task, as they initially struggled with the higher pace and efficient exploitation of weaknesses in the top flight, most exemplified by their 0–6 home loss to FC Luzern in the eight round. Winterthur still managed to secure a spot in the Super League for the next season, as they narrowly avoided the relegation play-off, ending the season one point above FC Sion. Despite this success and one year left on his contract, coach Berner departed to club following the conclusion of the season, to return to his boyhood club and cantonal rivals Grasshopper Club Zürich. Former FC Basel and Switzerland U21 coach Patrick Rahmen was announced as his replacement on 14 June 2023.
